摘要
22105工作面位于哈拉沟煤矿井田22上煤一盘区,宽度251.8m,推进长度1920.5m,回采面积48.4万m^(2),煤厚1.6~2.4m,煤层平均厚度1.8m,倾角为1°~3°,整体呈正坡回采,局部有波状起伏。对工作面初次压力及周期来压步距进行了分析,对回采过程中遇到的问题及解决措施进行了阐述,对以后类似综采工作面的回采具有指导意义。
The 22105 working face is located in the 22nd coal mining area of the Haragou Coal Mine.The width of the working face is 251.8 m,the advancing length is 1920.5 m,and the mining area is 484000 m^(2).The coal thickness is 1.6-2.4 m thick,with an average thickness of 1.8 m and an inclination angle of 1°-3°.The overall mining is on a straight slope,with local undulations.A detailed analysis is conducted on the initial pressure and periodic weighting step distance of the working face,and the problems encountered during the mining process and their solutions are elaborated in detail.It has guiding significance for the future mining of similar fully mechanized working faces.
