Building over former mines: a new guide for the UK

For land potentially affected by mining, the remediation requires an understanding of the lo ion and depth of mining and a key part of the process is a search of available mining records. However, older mining, particularly non-coal mining, is often unrecorded where it pre-dates statutory requirements for mine plans. Even where older records do exist, they may be incomplete or contain ...

Reducing harmful air emissions in underground mining BHP

With the workforce engaged, the team introduced an emissions-based maintenance project for the mine’s underground vehicle fleet. Maintenance activities relevant to DPM emissions were reviewed and exhaust DPM limits set that vehicles had to pass to be put back into service; failure to meet these limits triggered further maintenance. This led to a 40 per cent reduction in DPM emissions from ...

The principal functions of underground mine pillars are to stabilize openings and to carry the load of overlying rock strata. They are often partially or completely recovered at a later stage when their stabilizing effect is no longer required. For economic reasons, an optimum-sized pillar is the smallest one satisfying safety requirements. Thus the pillar design problem consists of ...

A key design aspect of room-and-pillar coal mines is the panel width or number of entries in a panel , which affects unit mining costs and productivity. Traditional mine design approaches do not facilitate optimisation of unit mining costs and productivity as a function of the panel width. Discrete event simulation can be used to facilitate optimal panel width selection that minimises unit ...
