RELIABILITY AND RISK OF FULLY MECHANIZED FACE OF COAL MINE WITH HIGH OUTPUT AND HIGH EFFICIENCY

As production is very concentrative in the coal mine with high output and high efficlency, ithas to undertake even more risk correspondingly. Fully mechanized face is the core of the coal mine withhigh output and high efficiency. This paper conlputes and distributes reliability of fully mechanized face;analyses its fault structure qulitativly and quantitatively, defines its fault model and computed arised probability of the fault model; finally, decides its risk degree.
