Mine Working and Coal Seam Assessment

Developing land or extending properties in an area with a coal mining legacy will require you to carry out a coal seam survey before your project can be completed. It can be a daunting and potentially expensive process, which is why it is so important to partner with us. We are an experienced and suitably qualified contractor with a good working relationship with The Coal Authority, enabling us to provide you with a fast, safe and economical solution.

Whether you simply require a drilling contractor or you need the services of one of our trusted industry partners to prepare a CMRA and report, we will supply you with an easy and budget friendly turnkey solution.

We are the safe pair of hands.

Why is This Necessary?

The conditions below ground level in areas previously mined for coal can present risks to development. Untreated shafts, tunnels or seams beneath the surface could create areas of weakness that will compromise the stability of your build.

To pass the planning stage, The Coal Authority must be satisfied that the ground you are building on does not pose a threat to your project and the only way to confirm this is to have a series of boreholes drilled to gain a profile of the ground (usually 3 x 30m.)


This type of work must be carried out with a Permit to Drill in place from The Coal Authority PRIOR to work commencing. Drilling work is closely scrutinised and monitored by The Coal Authority, with strict restrictions on drilling methods.

As the owner or developer, you are responsible for ensuring all work is carried out by a competent contractor, so don’t take any chances.

We will liaise with all appropriate authorities on your behalf and apply for and file all relevant paperwork so that you don’t have to – and we do this at no extra cost to you!

Our Equipment



We have a selection of Rotary options to cover all types of site access requirements and scopes of work, using a variety of techniques and flush mediums.

We transport our rigs and ancillary equipment in-house without using low-loaders, making our mobilisation both cost effective and easy to accommodate, especially in residential areas.

Using Beretta and Comacchio rigs, we tick all the boxes for geotechnical work, including window sampling, coring, open hole drilling and augering.

Rotary drilling doesn’t need to break the bank and we are here to show you how

Window Sampling/DCP

Window Sampling/DCP

The Dando Terrier is a versatile, small machine that delivers an accurate analysis of the ground, creating very little disturbance to the site and the ground being sampled.

Ideal for minimum access or sensitive sites.

Cable Percussive

Cable Percussive

Cable Percussion is a trusted method of drilling unconsolidated ground. With various tooling options and casing diameters available, as well as UT100 capability and UXO survey compatible casing, our rigs are perfectly equipped for all types of site investigation or exploratory work
