特厚煤层大采高综放工作面设备安装设计与实践
|
摘要
斜沟煤矿现主采13~#煤层,井田范围内煤层平均厚度达13.88 m,为达到煤炭资源的高产高效回采效果,该矿在我国率先使用了大采高综放采煤方法,达到了年产1 500万t/a的目标。大采高综放工作面设备普遍结构尺寸较大,重量较重,为工作面设备的运输与安装带来较大的难度,对设备运输与安装提出了新的要求。依托斜沟煤矿23101大采高综放工作面设备和运输与安装工程实际,利用现场调研与工程类比的方法,重新规划了工作面设备的运输路线,对运输经过巷道提出了整改要求,对工作面设备安装进行了优化设计,提高了工作面设备安装速度,保障了工作面的安全高效运转。同时,也为斜沟煤矿后续工作面的设备安装提供了实践基础,为条件类似的矿井提供了借鉴。
The average thickness of 13# coal seam in Xiegou Coal Mine is 13.88 m.In order to achieve the goal of high-yield mining of coal resources,by using fully mechanized caving method with large mining height,the output was reached 15 million t/a.The equipment of fully mechanized caving face with large mining height is generally large in size and heavy in weight,which brings great difficulty to transportation and installation.According to the mining conditions of No.23101 fully mechanized caving face with large mining height,through field investigation and engineering analogy,the transportation route of working face equipment was redesigned,and the installation design was optimized,which improves the installation speed of equipment,ensures the safe production of working face,and also provides a reference for the equipment installation in other coal mines.
