【摘要】：星村煤矿3302综放工作面采深-1 196~-1 135 m之间,地压大,有冲击地压危险,巷道压力大,煤体破碎。为保证安全回采,通过分析采空区自燃特点,制订了以"降温控氧"为主导思想、以"架间打钻和两端头封堵"为主要措施的胶体防灭火技术方案,解决了工作面自燃隐患。
[Abstract]:The mining depth of No. 3302 fully mechanized caving face in Xingcun Coal Mine is between 1 196 ~ 1 ~ 135 m, the ground pressure is high, there is a danger of impact ground pressure, the roadway pressure is high, and the coal body is broken.In order to ensure safe mining, by analyzing the characteristics of spontaneous combustion in goaf, a technical scheme of colloidal fire prevention and extinguishing with "cooling and controlling oxygen" as the main measure and "drilling between shelves and plugging at both ends" as the main measure has been formulated to solve the hidden trouble of spontaneous combustion in the working face.
