分析了大阳煤矿的开采现状和问题,就该矿3＃煤层综放开采的可行性进行了煤层厚度、煤层硬度等6个方面的分析,认为该煤层进行综放开采是可行的,在工作面设备选型方面实现了小型化和轻型化,指出了改善顶煤冒放性、提高顶煤回采率和瓦斯防治是该矿进行综放开采的技术关键,并提出了相应的技术措施。
The status and problems of the mining in Dayang Mine are analyzed. The feasibility of fully mechanized top coal caving mining in No.3 seam of this mine is analyzed in 6 aspects such as coal seam thickness and coal seam hardness. It is considered that it is feasible for the coal seam to be fully mechanized caving. The miniaturization and light-weight of surface equipment are realized. It is pointed out that the key to improve top coal caving rate, increase top coal recovery rate and prevent and control gas is the fully mechanized top coal caving mining, and put forward corresponding technical measures.
