[目的及方法]针对突出矿井地质构造区域瓦斯动态赋存状况下煤巷快速掘进诱发瓦斯超限甚至煤与瓦斯突出这一工程问题,提出了集瓦斯地质分析、构造区域瓦斯治理钻孔设计优化、深孔爆破增透、预警管控等于一体的"多技术综合集成"瓦斯防治技术体系.[结果]在贵州省小屯煤矿 16中15运顺掘进范围地质构造区域的实践表明,"多技术综合集成"瓦斯防治技术实施后抽采钻孔瓦斯浓度显著提升,煤巷掘进工作面过构造区域掘进速度提升了 45.8%,实现了地质构造区煤巷安全快速掘进.[结论]该技术对完善地质构造区煤巷掘进瓦斯防治体系具有重要价值.
To address the engineering challenge of gas overruns and even coal and gas outbursts induced by rapid excavation of coal roadways under the condition of dynamic gas occurrence in geological tectonic regions of outburst-prone mines,a"multi-technology comprehensive integration"gas prevention and control technical system was proposed.This system integrates gas geology analysis,optimization of gas control drilling design in tectonic regions,deep-hole blasting for permeability enhancement,and early warning and management.Practice in the geological tectonic region during the excavation of the 16middle 15 transport roadway at Xiaotun Coal Mine in Guizhou Province demonstrated that after the implementation of the"multi-technology comprehensive integration"gas prevention and control technology,the gas concentration in drainage boreholes increased significantly,and the excavation speed of the coal roadway heading face through the tectonic region was improved by 45.8%.This achievement enabled safe and rapid excavation of coal roadways in geological tectonic areas.
