采空区煤炭自燃致因分析

为了分析导致采空区煤炭自燃的关键因素，以便采取针对性措施预防煤炭自燃事故的发生，利用层次分析法构建了采空区煤炭自燃致因层次模型，分析了采空区遗煤自然发火的各种致因，并计算采空区遗煤自然发火致因的权重，确定了导致采空区煤炭自燃的关键因素，可为预防采空区遗煤自燃提供可靠的理论依据。

Cause Aanalysis of Spontaneous Combustion of Coal in Gob

In order to analyze the key factor leading to spontaneous combustion of coal in the gob and take correspounding measures to prevent the occurrence of coal spontaneous combustion, the analytic hierarchy process was used to construct the hierarchical model for analyzing the spontaneous combustion cause of coal in the gob, various causes of spontaneous combustion of the residual coal in the gob were analyzed, the weight of spontaneous combustion caused by the residual coal in the gob was calculated, and the key factor leading to spontaneous combustion of coal in the gob was determined, all of these provided reliable theoretical basis for preventing spontaneous combustion of coal in the gob.
