薄煤层综采机组在煤矿的实验研究

Experimental Study of Fully Mechanized Coal Mining Unit in Thin Coal Seam in Coal Mine

结合某煤矿的开采实践,介绍了首采工作面地质条件,并针对薄煤层综采机组的技术改造和管理措施等进行了实验研究。研究结果显示:本次薄煤层综合采矿三级配备设备的选择比较适合顶板条件较好、煤层厚度为1.5 m左右、质地结构相对优良的工作环境,但在煤层结构比较复杂、开采难度大的工程中,其功效较难发挥。

Combined with the mining practice of a coal mine,the geological conditions of the first mining face are introduced.The experimental study was carried out on the technical transformation and management measures of the fully mechanized coal mining unit in thin coal seams.The results show that the selection of the third grade equipment for the comprehensive mining of thin coal seam is suitable for the better roof condition,and the thickness of the coal seam is about 1.5 m.The working environment is relatively good in texture structure,but it is difficult to exert its effect in the engineering with complex coal seam structure and high mining difficulty.
