浅析岩巷爆破装药量与CO生成量的关系

摘要

The variety of CO concentration will result curve fluctuation of monitoring probe in each construction site during rock roadway blasting. In order to prevent security accidents led to high CO concentration, the ventilation Dept.of Sima Coal Industry Co.,Ltd. has collected the data of charge weight,drilling number,hole depth,CO concentration,CH4 concentration and caving rock quantity in rock roadway blasting of high level suction roadway at 1208 face,and analyzed their corresponding relationship,which provided basis for the safety blasting in coal mines.%巷道爆破掘进时产生 CO 气体浓度的变化会导致各施工点监控探头曲线发生波动，为防止爆破时产生的 CO 浓度过高而导致的安全事故，通过对1208高抽巷爆破掘进时装药量、钻孔数、孔深、CO 浓度、CH4浓度和落岩量等数据进行收集，分析判断其相应的关系，为矿井井巷安全爆破作业提供了依据。
