Case Studies

A potential ground gas risk was identified to site operatives during the treatment of former mine workings.

GGS presence on site ensured that a safe system of work was in place to enable the intrusive works to continue and remain on schedule.

GGS provided advice on expected gas protection standards and worked with the installation team to significantly improve standards.

Our client had confidence that installation of gas protection was correct and local planning authorities could discharge planning conditions.

Surface emissions survey data proved that site activity had not changed the ground gas regime or introduced vertical preferential pathways.

GGS provided a detailed continuous receptor monitoring programme to provide evidence that existing gas protection measures were sufficient.

GGS used a conceptual site model for a client who wanted to understand the risk to their development from coal measures before development.

GGS provided sub-floor void monitoring services after installed gas protection measures couldn’t be verified.
