浅析煤层自燃发火综合防治技术

Synthentic Protection Technology of Spontaneous Combustion in Coal Strata in Caomei Company

在中厚煤层的开采中,通过采用无煤柱开采、分层开采与放顶煤相结合的方法,杜绝了因煤炭丢失而形成的碎煤体产生发热源;采取对变形失效密闭重新构筑,对开采方式以及对通风系统进行优化等措施,以尽量减少采空区的漏风;采用阻化剂和预防性注浆,来阻止煤炭自燃的发展;利用监测监控系统和人工检测网络,能够及时发现火患苗头,为适时采取措施提供了保障。

In mining medium - thick coal strata, by using the method of non - pillar mining, slice mining and caving method, fever caused by conny source which was formed by coal losing can be prevented. By re - building confination failure due to deformation, optimizing ventilation systems, and minimizing ventilation system, leakage in exhausted areas can be decreased; by using resistance agent and preventive grouting, development of spontaneous combustion of coal can be prevented; by using monitoring system and the manual testing network, fire signs can be discovered at once. Thus, it can provide guarantee for preventing spontaneous combustionin coal strata.
