Fundamentals of modern ground control management in ...

01-09-2020· This paper summarised the typical pro-active ground control management system (PGCMS) implemented in various Australian underground coal mines. Australia produces approximately 100 million tonnes a year of metallurgical and thermal coal from approximately 30 of the world’s safest longwall mines operating in New South Wales and Queensland.

Gas Control | Introduction | underground COAL

Gas Control. Some mines do not have a gas problem of any type, the quantity of gas in the coal being so low that only small percentages (or even zero) are ever detected in the air. In such mines, other than continuously or regularly checking gas levels to ensure conditions have not changed, no special processes are required.

Strata Control | Introduction | underground COAL

STRATA CONTROL. General. The term "strata control" generally refers to controlling the strata to maintain stability around the mine openings underground where operations are or will be taking place. It does not cover such subjects as subsidence or strata remote from the workings.

Risk precontrol continuum and risk gradient control in ...

01-09-2019· Underground coal mining is recognized all over the world as one of the riskiest industrial operations. To improve the safety management model in underground coal mines from passive management to active management, the risk precontrol continuum and risk gradient control in underground coal mining are proposed in this paper.

Outburst Control | Introduction | underground COAL

Outburst Control. Early methods of mining in locations liable to outburst tended to involve giving the face a "shake" (by bumping it with the miner cutting head or using explosives) to initiate an outburst at a time when the crew was prepared for it, should one be imminent.

Best Practices For Dust Control In Coal Mining

U.S. underground coal mine workers. • During 1980–2005, over $39 billion in CWP benefits were paid to underground coal miners and their families. • Recent x-ray surveillance data for 2000–2006 show an increase in CWP cases. Nearly 8% of examined underground coal miners with 25 or more years of experience were diagnosed with CWP.

Coal-seam fire - Wikipedia

A coal-seam fire is a burning of an outcrop or underground coal seam.Most coal-seam fires exhibit smoldering combustion, particularly underground coal-seam fires, because of limited atmospheric oxygen availability. Coal-seam fire instances on Earth date back several million years. Due to thermal insulation and the avoidance of rain/snow extinguishment by the crust, underground coal-seam fires ...
