急倾斜煤层采煤法单采能力提高途径探讨

Discussion on Improvement Approaches of Unit Output for Steep Coal Seam Mining Methods

介绍了走向长壁、掩护支架、斜坡、水平分段放顶煤四种急倾斜煤层开采方法,从通风条件、巷道掘进率、回采率、机械化程度及开采效益等方面分析了急倾斜煤层开采中存在的主要问题,并对上述四种模式提出了相应的提高单产能力的发展方向,可为急倾斜煤层采煤方法的选择提供借鉴意义。

The steep coal seam mining methods of long wall mining, shield mining, slope mining, and horizontal section top coal caving were introduced, the main problems of steep coal seam mining were analyzed from the views of ventilation conditions, roadway drivage rate, recovery rate, mechanization degree of mining and mining benefits, and the development direction of the four mining modes was proposed for unit output improvement, which could provide references for the selection of mining method for steep coal seam.
