【摘要】：矿井煤炭自燃火灾是煤矿的主要自然灾害之一,其中大部分的自燃火灾都发生在采空区。在采空区煤炭自燃火灾发生前,对自燃危险的程度进行评估,依据评价结果及其中间结果,采取有重点有针对性地防灭火措施,从而降低或消除采空区自燃危险性,为煤矿采空区自燃火灾的治理工作提供科学可靠的依据。本文首先对综采工作面采空区煤炭自燃的内因和外因进行了分析,并选取了综采工作面采空区煤炭自燃危险性的评价指标,在此基础上建立了综采工作面采空区煤炭自燃危险性综合评价指标体系,进一步采用层次分析法确定了评价指标的权重和采用专家评判法确定了评价指标的隶属度。基于模糊综合评价的理论,建立了综采工作面采空区煤炭自燃危险性模糊综合评价模型,根据评分等级法确定综采工作面采空区煤炭自燃危险性的等级。根据综采工作面采空区自燃危险性模糊综合评价模型,借助于计算机辅助软件VB和Excel,编写出综采工作面采空区煤炭自燃危险性综合评价软件,实现了评价的自动化,提高了评价工作的效率。最后,本文结合某矿10414工作面的实际情况,采用评价软件对该工作面采空区进行了评价,并根据评价的结果,提出了相应的自燃防治措施。
[Abstract]:Coal spontaneous fire is one of the main natural disasters in coal mine, most of which occur in goaf. Before the spontaneous combustion of coal in goaf, the degree of the danger of spontaneous combustion is evaluated. According to the evaluation result and the intermediate result, some measures are taken to prevent and extinguish the fire, so as to reduce or eliminate the danger of spontaneous combustion in goaf. It provides a scientific and reliable basis for the control of spontaneous combustion in goaf. In this paper, the internal and external causes of coal spontaneous combustion in goaf of fully mechanized mining face are analyzed, and the evaluation index of coal spontaneous combustion risk in goaf of fully mechanized coal mining face is selected. On this basis, the comprehensive evaluation index system of coal spontaneous combustion risk in goaf of fully mechanized mining face is established, and the weight of evaluation index is determined by AHP and the membership degree of evaluation index is determined by expert evaluation method. Based on the theory of fuzzy comprehensive evaluation, a fuzzy comprehensive evaluation model of coal spontaneous combustion risk in goaf of fully mechanized coal mining face is established, and the grade of coal spontaneous combustion risk in goaf of fully mechanized coal face is determined according to the scoring grade method. According to the fuzzy comprehensive evaluation model of spontaneous combustion risk in goaf of fully mechanized coal mining face, the comprehensive evaluation software of coal spontaneous combustion risk in goaf of fully mechanized coal face is compiled by means of computer aided software VB and Excel, and the evaluation automation is realized. The efficiency of evaluation is improved. Finally, combined with the actual situation of No. 10414 face in a certain mine, the goaf of the working face is evaluated by using the evaluation software, and according to the evaluation results, the corresponding measures of preventing and controlling spontaneous combustion are put forward.
