对安家岭煤矿B901综放工作面进行了为期近1个月的工艺观测,并应用可靠性理论对回采工艺系统可靠性进行了分析。从具体内容上提出了综放工艺所需观测的环节,而且系统地提出了如何分析综放工作面回采系统的可靠性,实现了工作面的人机工时利用率的提高及工作面设备故障的减少。 The process observation of B901 fully mechanized coal caving face in Anjialing coal mine was carried out for nearly 1 month, and the reliability of the mining process system was analyzed with the reliability theory. From the concrete content, it puts forward the necessary observation part of the fully mechanized top coal caving technology, and systematically puts forward how to analyze the reliability of the mining system in fully mechanized top coal caving face to improve the man-hour utilization rate of the working face and the equipment failure in the working face cut back.
