摘要
为解决赵庄煤矿3303工作面抽采效果不佳的问题,通过系统收集工作面高位钻孔抽采数据,并对高位钻孔抽采数据收集整理及现场跟踪考察,分析了高位钻孔抽采效果,最终提出钻孔参数优化方案。
To solve the poor extraction effect of 3303 working face in Zhaozhuang coal mine,by systematic col-lecting extraction date from highly-located borehole,analyzing the high drilling extraction date and the tracking in-vestigation,the extraction effect in highly-located borehole was analyzed.Finally optimization scheme of drilling pa-rameters is put forward,and can provide the basis for borehole layout of similar conditions.
