急倾斜煤层综放开采相似模拟实验研究

Study on the Fully Mechanized Top Coal Caving Mining in the Deeply Inclined Seam by the Analogous Simulation Experiment

通过进行急倾斜煤层综放开采的相似模拟实验,对综放开采的合理放煤方式及放煤步距进行了研究。研究结果表明:综合考虑劳动组织、含矸率、煤矸分界面的混矸层厚度等影响因素,确定单轮间隔放煤方式为最优放煤方式,最优放煤步距为一刀一放。

Through carrying on the analogous simulation experiment in the deeply inclined fully mechanized top coal caving mining face, studies the optimum top coal caving manner and pace in the fully mechanized top coal caving mining. The findings indicates that： by taking labor organization, waste rock involved rate, the thickness of waste rock mixture seam in the interface of rock and mine into consideration, it can be ensured that the manner of top coal caving one gate interval another is the best, the optimum top coal caving pace is caving after mining.
