煤矸石山注浆灭火治理

Fire Control of Coal Gangue Heaps with Grouting Fire Extinguishing

针对煤矸石自燃会对生态环境和人类的安全健康产生不良影响,提出了高效快捷的治理矸石山自燃措施,且针对煤矸石体具有松散不稳定的特点,通过现场钻进工艺的试验对比,改进钻进方式,提高了矸石山钻孔成孔率,并且能够高效快捷的对矸石山进行灭火,也有效避免矸石山灭火后的复燃。

Spontaneous combustion of coal gangue has an adverse impact on both the ecological environment and human health and safety.This paper proposed a fast and efficient measure to control the spontaneous combustion of waste gangue heaps.In view of the loose and unstable coal gangue,the comparison of field drilling process tests and improvement of the drilling methods could increase the probability of hole formation in the waste gangue heaps,efficiently extinguish the fire,and effectively prevent the reignition.
