The safety performance of coal mines is influenced not solely by governmental safety regulation, but by their embedded non-safety regulation games with their internal and external related industries. Therefore, to better understand the safety performances disparity in SOCMs and TVCMs, an embedded non...
Track Transportation It is the main mode of underground transportation in metal mines. Its basic task is to transport ore, waste rock, materials, equipment, personnel, etc. Some large open-pit iron mines also use track transport systems to transport ore and waste rock. The advantages of track ...
Outburst coal Pore Nitrogen adsorption Coal and gas outburst 1. Introduction Coal and gas outburst is one of the most serious disasters in underground coal mines [1], [2], [3], which can be attributed to several factors: high methane pressure, high methane content, high in-situ stress, di...
Conclusion shows that strengthening the research on basic hazard theory, particularly on the identification and control of the third kind of hazard, is very helpful to the improvement of safety management in coalmines. 展开 关键词: the third type of hazard organizational accidents organizational men ...
Claystone is a sedimentary rock made of more than 67% clay-size particles. 09 of 24 Coal From a Utah mine, this coal is a black, carbon-rich rock derived mostly from ancient plant remains. ThoughtCo / Andrew Alden Coalis fossilizedpeat, dead plant material that once piled deep on the bo...
Frequent occurrence of gas accidents is the main factor restricting the safe production in China's coal mines.In this paper,the factors that influence the gas explosion in heading face were identified and analyzed based on the theory of three types of dangerous sources,and on this basis,a safet...
Exploration for human factors in the design of coal-mine safety and rescue devices Recent years production accidents keep appearing in coal-mines of our country. The author analyzes different factors that may cause accident and comes to t... W Zeng - International Conference on Computer-aided Ind...
Coal, one of the most important primary fossil fuels, a solid carbon-rich material, usually brown or black, that most often occurs in stratified sedimentary deposits, which may later be subjected to high temperatures and pressures during mountain buildin
Coke, solid residue remaining after certain types of bituminous coals are heated to a high temperature out of contact with air until substantially all of the volatile constituents have been driven off. The residue is chiefly carbon, with minor amounts of
set up testing stations. Similar action was taken in theUnited Statesa few years later. The result was a series of special dynamites approved for use in gassy and dusty coal mines when used in the specified manner. Their blasting action was not as good as that of black powder, but they ...
