摘要
煤层自燃发火是煤矿安全的大敌。水力采煤技术作为一种机械化采煤技术 ,在我国历经 40余年的发展和完善 ,已趋于成熟。在适宜地质条件下 ,可取得更好的社会效益和经济效益。特别是在防治自燃发火等方面 ,水力采煤技术更具有明显优势。文章总结了水采矿井煤层自燃发火特点 ,分析了原因 ,提出了防治技术及其发展方向。
Spontaneous combustion of coal seam poses great hazards to safety mining operations.After 40 more years of development,the mechanized hydromining system has become increasingly mature.When applied under appropriate geological conditions,it can yield favorable socio economic result.With regard to prevention of spontaneous combustion,the advantage of this method is more prominent.The paper presents an analysis of the characteristics and cause of spontaneous combustion occurring in hydromines.Finally the preventive technique is proposed,together with a discussion of its developing trend.
