Mining & Land Stabilisation @ JPB
Virtually every county and region of the United Kingdom has, at some period in the past, been subject to underground mining for a variety of minerals.
The impact of such workings, some as old as the Neolithic period, has been largely unrecorded until recent times. Today the hazards created by such workings, particularly in coal, limestone, chalk and iron ores, are widely recognised.
Hazards from underground cavitation vary with the nature of the mineral and style of mining, but typically include surface subsidence and structural failure in buildings.
Research - use of JPB’s archive of mining and ground conditions (including several thousand original mine plans).
Coal Authority Mining Risk Assesment - Initial low-cost, archive-based, mining risk assessment with recommendations for ground investigation and stabilisation, if appropriate.
Investigation of Old Mine Working - Design and supervision of drilling and geophysical investigations to prove the condition of old workings or mined ground.
Mine Workings Stabilisation - Design and supervision of the grouting or bulk infilling of old mine workings in coal, limestone, sandstone, and other bedded and vein minerals.
Mineshaft Stabilisation - Design and supervision of shaft searches and treatment; liaison with the Coal Authority where appropriate; preparation of completion reports to satisfy local authorities and NHBC.
Subsidence Engineering - Subsidence modelling and prediction; surface subsidence monitoring; property condition surveys; recommended structural precautions. Monitoring of brine subsidence effects, and related planning and structural advice, in the Midlands saltfields.
Opencast Mining and Bulk Earthworks - Earthworks design and optimisation of muckshift; specification and control of opencast backfilling and bulk earthmoving.
Mineshaft Risk Assessment - Risk assessment to aid house buyers.
