Having problems with a planning application? /or you need an intrusive drilling or borehole investigation following on from a coal mine risk report or CMRA? Let Geoinvestigate Microdrill quote for your coal mine working, mineshaft, mine adit or mine working investigation in Barnsley, Doncaster, Rotherham, Sheffield or South Yorkshire. We are Site investigation and coal mining experts and drill coal and mine workings routinely all over the country from Bristol to Glasgow including Barnsley, Doncaster, Sheffield and Rotherham. Barnsley & Doncaster Council SYMAS Geotechnology and Mining Searches recommend Geoinvestigate coal drilling & mine drilling services on former coal mining areas.
Barnsley Council SYMAS recommend Geoinvestigate Microdrill
SYMAS (South Yorkshire Mines Advisory Service) and their mining engineers provide technical advice to Barnsley Council (BMBC) and Doncaster Council and South Yorkshire local planning authorities (LPA’s) and their Building Control departments on all aspects of ground stability issues and mine hazard whether it be mine shafts, mine adits, mine entries, mining subsidence, mine working collapse colliery tip stability or hazardous mine gas.
After hearing about the advantages of Geoinvestigates new coal microdrill SYMAS and their coal mining consultants were keen to recommend our new Microdrill for coal and mine drilling. This is what they had to say

Advantages of Geoinvestigate Microdrill
Want to know why SYMAS recommends Geoinvestigate Microdrill? These are the advantages of using Microdrill for coal and mine working investigation that SYMAS were told about -
No wonder then that when being provided with the above facts as well as the following images showing Microdrill’s small size and obvious suitability for restricted access coal and mine working drilling in gardens, courtyards and through gates and narrow pathways that SYMAS like the UK Coal Authority were quick to see the advantages of this new coal drilling system. Hardly surprising then that SYMAS now recommend Geoinvestigate Microdrill for mine risk and mine hazard drilling investigation.
Geoinvestigates New Coal Microdrill = 2 x Safer Drilling
Microdrill is doubly (2x) safer because drilling is done not only with water but with very small amounts of water. We also constantly monitor for several mine gases while we drill. The above image shows black coal in the water flush returned from a depth of 8m establishing that at this location the coal seam is either unworked or the drill has penetrated a remnant coal pillar in a room and pillar working. On this job further Boreholes confirmed that the site had indeed been extensively undermined by room and pillar methods at very shallow depth subsequently requiring pressure grouting to stabilise the ground before building could proceed safely
Your Mine Risk Report (CMRA) Is Likely To Need Drilling
According to a Barnsley mining source 75% of mine risk reports or Coal mining risk assessment (CMRA) reports end up needing further intrusive investigation. More often than not this is carried out using Boreholes. So in Barnsley, Doncaster, Sheffield, Rotherham and South Yorkshire following a coal mine risk report you are likely to need a drilling investigation together with a supporting technical report by a coal mining specialist or coal mining consultant (CMC) as well. Geoinvestigate Microdrill can provide this for you as well as a specialist mining report on the findings of the borehole investigation. Geoinvestigate provides a full 1 stop service including mining investigation and consultancy. Geoinvestigate’s coal drilling investigations and Ground stability reports and mine risk reports or CMRAs are Coal Authority and Local Authority compliant.
Because 75% of coal mine risk reports or CMRAs require further intrusive investigation mostly using Boreholes there is a very good chance that the mine risk report you get will recommend drilling, Boreholes or open hole probing to locate drift/soil thickness and coal and mine working depth. Geoinvestigate can provide this service for your building development or construction project wherever your site is in Barnsley, Doncaster, Sheffield, Rotherham or South Yorkshire.
While 75% of CMRAs may end up in drilling typically less than 10% require further mitigation such as special Foundation design and/or systematic drilling and pressure grouting. While occasionally it may be possible to move a new building to a safer part of the site such flexibility is a rare luxury these days as development sites get smaller.
Drilling Is Never A Waste
Drilling is never a waste of money because it provides conclusive proof about whether a site has been mined or not. Drilling can also save you money on unnecessary expensive raft foundations. Geoinvestigate has had first-hand experience of several jobs in recent years where house builders have been recommended rafts but which drilling showed to be completely unnecessary saving many £1000s. Another benefit is that once drilled a property shouldn’t need a repeat or new CMRA the next time it’s put on the market or you need to raise a 2nd mortgage on the property or if the building is to be extended.
Mine Shafts, Mine Adits or Mine Entries
If you have a mine shaft on your property or in a neighbour’s property but near to your house you will almost certainly require further intrusive investigation and a Ground stability report. In the case of mine shafts, mine adits, drifts, levels or mine entries this can be expensive. The investigation of vertical shafts requires that the drill rig and its operators have to be supported on a special safety platform capable of spanning a large deep void were the shaft collar to suddenly collapse and a void to appear. For this reason mine shaft investigation requires specialist knowledge and considerable expert coal mining knowledge.
Making A Planning Application? – Geoinvestigate Can Help
If you are submitting a planning application in Barnsley, Doncaster, Sheffield or Rotherham or South Yorkshire you may be advised by your Local Planning Authority, LPA or Building Control or perhaps SYMAS, the South Yorkshire Mining Advisory Service that you require a “Coal mining risk assessment”, mine risk report, ground stability coal report or CMRA.
This is because many parts of the region are on shallow coalfield or coal outcrop where your building development, property or construction project may be at risk from the presence of coal itself, coal outcrop working, coal mining subsidence, mine shafts, mine workings and/or toxic, flammable or explosive mine gas.
Very complex sites may be impacted by ground stability problems arising both from underground and surface mining or opencast coal mining. Mine spoil heaps, coal tips and colliery tips can pose surface stability hazards to development and require careful Site investigation.
On submission of a planning application on the Yorkshire or Nottingham coalfield you may be advised by the Coal Authority, Barnsley Council, Sheffield Council, Rotherham Council, Building Control or Doncaster Council Building Control perhaps via SYMAS South Yorkshire Mining Advisory Service that because your site lies in an area of higher mining risk or a Development High Risk Area or DHRA that you require a CMRA or Coal mining risk assessment. Therefore before submitting a planning application it’s always best to check if your site is on a DHRA and needs a mining risk report or CMRA. Checking can avoid lengthy delays in obtaining planning permission. You can also check using the Coal Authority – GOV.UK online mining service.
At Geoinvestigate our experts lead by Ross Nicolson BSc (Hons) MSc (Eng) CEng MIMMM can quickly check whether your development in Barnsley, Doncaster, Rotherham or Sheffield is on a DHRA and you need a coal mine risk report and we don’t charge for this service. We can also provide you with a CMRA, an intrusive drilling investigation and all the necessary specialist technical advice you need to get your development through planning in relation to coal legacy or other types of underground or opencast mining legacy whether its ironstone or iron ore mining, chalk, limestone, building stone, fireclay, flagstone, brine or slate mining.
Safe Coal & Mine Working Drilling With Water Flush
Coal drilling or mine probing is normally done using rotary open borehole techniques. Typically as a standard the UK Coal Authority require exploratory Boreholes to be drilled to 30m depth though some local authorities may accept shorter Boreholes of say <20m depth. In some instances this may be because other drills struggle to go deeper. Not Geoinvestigate Microdrill as this powerful yet compact coal and mineworking drill regularly achieves the depth required.
Because of serious safety concerns and risk to health investigative coal and mineworking drilling in close proximity to occupied buildings must be carried out using WATER FLUSH only. Geoinvestigate Microdrill uses only water flush with the additional advantage that only very small amounts of water enters the ground and workings with negligible risk of pushing large volumes of toxic coal and mine gases to the surface where they can pose a very serious hazard to the public or the drill operators themselves.
Geoinvestigate Are Site investigation & Mine Risk Experts
Geoinvestigate are experts in mine risk assessment in the Barnsley, Doncaster, Rotherham, Sheffield and South Yorkshire areas and elsewhere for that matter throughout the UK. We routinely carry out CMRA mine risk assessments, mine searches, mining searches and mine reports in the Yorkshire region together with follow-up drilling and ground gas survey investigations for coal mineworkings.
