倾斜长臂综采大倾角仰采技术的应用

介绍了三矿采用倾斜长壁大倾角仰采技术,对己15大倾角煤层进行开采,在仰采过程中人为调整伪倾斜,降低工作面仰采角度,使用台阶式仰采方法,保证推移千斤顶能够正常拉移支架,采煤机可以正常在运输机上行走,支架可以在10°的坡面上保持其稳定性,保证工作面安全推进。

Application of Inclined Long Arm Fully Mechanized Mining in Large Dip Angle

Introduced No.3 Coal mine utilized inclined longwall mining technology in the group coal seam15 large dip angle coal seam mining,in the process of it,we artificially adjusted the dip angle to lower the angle of the working face,using terraced overhead mining method to ensured the normal order of the jack moving support,coal winning machine can be normal in walking on the transport planes,bracket can maintain its stability in the side slope of 10°,ensured the safety of working face advancing.
