煤矿生产过程中,如何采取有效措施,避免煤炭自燃,一直困扰着煤矿企业,因为这不但危机矿工生命安全,而且还会给矿井带来难以估量的损失。本文主要结合平煤大庄矿煤层自燃发火的特性,和自燃发火的早期预报指标。并根据采煤工作面自燃发火的实际情况,采取了注灭火剂、挂挡风障和导风障以及充填采空区等措施,有力的制止了采煤工作面自燃发火,避免矿井资源损失。
In the process of coal mine production, how to take effective measures to prevent spontaneous combustion of coal has plagued the coal mining enterprises because it will not only endanger the life and safety of the miners, but also bring immeasurable losses to the mine. This paper combines the characteristics of spontaneous combustion of coal seam in Pingdingshan Dazhuang Coal Mine and the index of early prediction of spontaneous combustion. In accordance with the actual situation of spontaneous combustion in coal mining face, measures such as fire extinguishing agent, hanging wind barrier and wind-induced obstacle and filling gob area were taken according to the actual situation of coal spontaneous combustion in coal mining face, which effectively prevented spontaneous combustion of coalface and avoided mine resource loss.
