摘要
针对缓倾斜煤层角度较大造成的连续采煤机设备运行和开采困难等问题,提出采用调伪斜布置巷道、选择履带式运输设备以及调整连续采煤机进刀方式等,保障连续采煤机及后配套设备能够在合理的角度范围之内运行,将三角遗煤降到最低,实现连续采煤机在缓倾斜煤层条件下的安全高效开采。实践表明:东坡煤矿缓倾斜煤层连续采煤机开采取得了月均进尺550 m/单巷,月均回采煤炭5.5万t,为连续采煤机在我国缓倾斜煤层的应用提供了宝贵经验。
To solve the problems in the operation of continuous miners in mining caused by big-ger-angled gently inclined coal seam, this paper proposes such strategies as adjustment on apparent dip in roadway arrangement, choice of crawler type continuous transport system, and adjustment in feeding patterns of the continuous miner, which can insure the operation of the continuous miner and its post-support equipment in reasonable angles, minimize the amount of triangle residual coal, and realize the safe and high efficient mining in gently inclined coal seams with the continuous miner. The applica-tion of these above-mentioned strategies in real practice in Dongpo Coalmine brings satisfactory results：1） Mining in gently inclined coal seams with continuous miners has achieved monthly advance of 550 meters per single entry on average; 2） monthly extraction of coal has reached 55 000 tons averagely. This offers valuable reference for the application of continuous miners in gently inclined coal seams in China.
