Abstract: To solve the problems in the operation of continuous miners in mining caused by bigger-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 application 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.
