摘要
文章以峰峰集团有限公司大淑村矿为实施矿井,在煤炭科学研究总院抚顺分院科研人员指导下进行了超前钻孔瓦斯排放半径的研究。利用合理化布孔、确定规律性考察指标,掌握了适合大淑村矿的超前钻孔瓦斯排放半径快速测定方法。
Taking Dashucun Coal Mine of Fengfeng Co. , Ltd. as implementing mine, under Fushun Branch of China Coal Research Institute research personnels＇ instruction, we layed the borings rationally, ascertained disciplinary guide line. At last we mastered the method of quickly mensurating the effectual radius of the leading borings.
