柳湾煤矿小窑火区综合治理技术应用
|
摘要
为了保证柳湾煤矿二采区巷道安全掘进,同时最大程度的回采煤炭资源,针对二采区小窑火区的现状,提出了采取地表灌浆隔氧、注凝胶降温和井上下堵漏隔氧的综合治理方法,共同发挥灭火作用。现场技术应用表明,火区得到了有效控制,为其它煤矿火区治理工作提供了借鉴经验。
In order to ensure the safe mining of the second mining area for Liuwan Mine and the maximal degree mining,according to the present situation of small coal mine fire area, the comprehensive control methods of surface grouting oxygen insulation, injected gel cooling and plugging oxygen insulation for the upper lower mine were preserved to play an important role for fire extinguishing. The results showed that the fire area could be effectively controlled, the reference experience was provided for fire area control work of other mines.
