摘要
针对朱家店煤矿在0401工作面薄煤层区域技改小滚筒确保正常回采的试验,分析在薄煤层使用小直径滚筒回采的各种参数,对比对在回采工程中原煤与次煤产量的变化及其带来的直接与间接经济效益。实践表明此次技改试验成功,为薄煤层快速开采开辟了一条可行的技术途径。
To ensure the normal stoping test of the small-diameter roller in the area of 0401 working face of the coal mine in Zhujiadian coal mine, the paper analyzes the various parameters of the small-diameter roller in the thin coal seam. The change of raw coal and secondary coal in the mining engineering and the direct and indirect economic benefit brought by the comparison are compared. The practice shows that this technical reform test has succeeded in opening up a feasible technical approach for the rapid mining of the thin coal seam.
