磁窑沟矿10202工作面漏风封堵防灭火

Plugging Air Leakage for Fire Prevention in 10202 Working Face of Ciyaogou Mine

本文根据磁窑沟矿矿井煤层厚度变化较大,10202工作面采用一次采全高综采机械化采煤方法,采空区存在部分顶煤,煤层内生裂隙发育,易引起采空区浮煤自燃的实际情况,通过采取注浆、注氮、注阻化剂外加堵漏等防灭火措施,减少了采空区漏风,对防治采空区自燃取得了较好的效果。

The fully mechanized mechanized coal mining method of mining overall height at one time is adopted for 10202 working face, the internal fissures in the coal seam of some top coal in the goaf area are developed, which may cause spontaneous combustion of the float coal in the goaf area. The adoption of grouting, nitrogen injection, injection inhibitors, plugging and other fire prevention measures reduces the air leakage in the goaf and has achieved the good results in the prevention of spontaneous combustion in the goaf.
