易自燃突出煤层无煤柱开采技术研究

Research on Mining Technology of Non Coal Pillar in Easy Spontaneous Combustion Outburst Coal Seam

介绍了易自燃突出煤层的特点和自燃原因,指出其开采难的原因,并介绍了无煤柱开采技术,包括其原理和使用的煤层条件,从防漏风、防灭火以及推进度方面指出了该项技术中的难点。最后,从利用风压规律、管理采空区、墙体堵漏、采空区自然发火标志性气体监控等技术,防止火情、调节风压以及探求各因素之间的关系,掌握各因素间影响规律等几个角度提出了解决采空区自然发火的对策。

It introduces the characteristics and causes of easy spontaneous combustion outburst coal seam, at the same time, it points out the reasons for its difficulty in mining. In addition, also introduces the mining technology without coal column, which includes its principle and coal seam conditions, and points out the difficulties in this technology from the aspects of air leakage prevention, fire extinguishing and propulsive degree. Finally, it puts forwards some countermeasures to solve the spontaneous combustion of goaf from the perspective of preventing fire, turning the adjustable wind pressure, exploring the relationship and grasping the law of influence among various factors with the technology of using the law of wind pressure, managing the goaf, wall plugging and gas monitoring of natural fire.
