Risk analysis on gas accidents in coalmine working face
Gas is one kind of important disasters in coal mines and can cause great economic loss and human death and injuries,affecting production of mine.Preventing gas accidents is the most important work in the coal production enterprise.Combining the situation of coal mine,safety checklist,fault tree analysis and preliminary hazard analysis are chosen from many system analysis methods to assay the danger of gas in mine workface.By analyzing the danger of gas,the result indicates that gas accidents happening in mine workface result from workers unsafe behavior and objects unsafe situation.Moreover,the workers play an important role in the accident.So,we should take action fiom the two aspects especially pay more attention to the administration of workers.At the same time,with reference to the experience of mining at home and abroad,in allusion to the analysis results,this paper brings forward security technology measures to instruct safety production of coal mine.It has great guidance meaning in preventing gas accidents.
