摘要
为了简化掘进巷道支护工序,降低巷道支护成本,提高巷道掘进速度,郑煤集团白坪煤矿在井下掘进工作面根据不同的地质条件设计支护方案,利用差异化支护对井下巷道进行支护。通过数据分析,不但保证施工安全、满足生产需要,而且显著提高了经济效益,降低了生产成本,实现了巷道安全、快速掘进。为今后在煤炭行业中推广差异化支护提供了理论依据。
in order to simplify the drivage roadway support process, reduce the cost of support, increase the speed of roadway drivage, zhengmei jituan Bai Ping in tunneling working face in coal mine design support scheme according to different geological conditions, the use of differentiation on underground roadway bolting support mode. Through data analysis, not only ensure construction safety, meet the need of pro- duetion, and improve the economic efficiency, reduce the production cost, achieve the safe and speedy drivage roadway. For the iuture provide a theoretical basis for differentiation support in coal mine.
