摘要
针对曹村矿矸石山自燃火区特点及现场勘查状况,结合以往矸石山灭火经验,提出以注浆法、注胶为主,辅以直接挖除火源、黄土混合碾压、黄土覆盖的综合治理方案,论述了注浆法灭火原理及灭火工程工艺设计的具体措施,该方法在现场实施效果良好。
On the basis of the characteristics of spontaneous fire zone of coal gangue dump in Cao village and the site investigation as well as the previous experience on the fire extinguish- ment, a comprehensive control program was put forward, namely preferential grouting by aid of excavating fire source directly followed by compacting and covering with the loess. The mecha- nism of fire extinguishment by grouting and the specific measurement of the process design on the fire extinguishing engineering were also explained. A satisfied field performance was obtained, proving to be a rapid, economic and efficient method to control the spontaneous combustion of coal gangue dump.
