河南天安煤業(yè)5.15煤矸石山自燃爆炸成因分析與防治研究

摘要： 2005年5月15日、16日,河南天安煤業(yè)四礦矸石山先后發(fā)生兩次自燃爆炸災害,造成8人遇難,122人受傷,造成生命財產的重大損失.首先介紹了天安煤業(yè)四礦煤矸石的物質組成,分析了其致災原因:高含硫煤矸石的存在是引起煤矸石山自燃的決定因素;煤矸石的堆積方式以及有效的粒徑組成在一定程度上決定了煤矸石的透氣性,是引起煤矸石山自燃的促進條件;突發(fā)降雨應是本次災害的主要導火索.在燃料含量一定,清除比較困難,燃燒已開始并還在不斷堆積矸石的情況下,降溫和隔氧顯得尤為重要.針對本矸石山的實際情況,提出了采用注漿法為主,輔以高溫區(qū)域表面噴射漿液、挖掘溝槽、表面覆蓋等滅火方法,并對以后矸石山自燃免災方向進行了展望大. Abstract： The spontaneous combustion and explosion of waste dump happened two times successively at the No.4 Mine of Tianan Coal Mine Group on May 15 and 16,2005,which led 8 died,122 injured and heavy losses of life and property.This article introduces firstly the physical makeup of coal gangue here and analyzes its reasons resulting in hazards:the existence of coal gangue bearing rich sulphur is the conclusive factor that causes the spontaneous combustion,the dump mode of coal gangue and the effective particle-size makeup decide the air permeability of coal gangue to a certain extent,which accelerates the spontaneous combustion;the sudden rainfall is the main fuse.When the content is definite,it is difficult to clear away and the combustion has already began and the dump of coal gangue has been continued,more attention should be paid to the cooling and oxygen isolation.In view of the coal gangue here,this article provides some methods that takes mainly grouting and subsidiarily sprays the slurry onto high-temperature surface as well as digging ditches and gurface eoverage.Besides,it predicts the future of the spontaneous combustion of coal gangue keeping from hazards. 作 者： 邢永強    張璋    潘元慶    溫宏亮    商真平    Xing Yongqiang    Zhang Zhang    Pan Yuanqing    Wen Hongliang    Shang Zhenpin   作者單位： 邢永強,張璋,潘元慶,溫宏亮,Xing Yongqiang,Zhang Zhang,Pan Yuanqing,Wen Hongliang(河南省國土資源科學研究院,鄭州,450016)
