前言 黄泥灌浆法已被国内外认为是一种行之有效的井下防灭火方法,在我国自燃发火矿井中已广泛应用。 西南地区自燃发火严重的矿井,一般地处山区,黄土极其缺乏,国内其它矿区,虽然有土源,但势必与农业争土,摧毁大片可耕农田,为了贯彻以农业为基础的方针,加强工农联盟,以便充分发挥现有灌浆系统的作用,确保安全生产,因地制宜地寻找灌浆的代用材料,已成为迫切需要解决的大课题。 根据煤炭部科研计划及四川省煤管局指示,由芙蓉矿务局、重庆煤炭科学研究所组成三结合试验小组,进行飞仙关页岩粉碎制浆的防灭火研究工作,并确定在芙蓉矿务局杉木树煤矿南井作试验。
Foreword Huang mud grouting method has been considered as an effective underground fire extinguishing method at home and abroad, has been widely used in spontaneous combustion of coal mines in our country. In Southwest China, spontaneous fires are very serious in mines. Generally, they are located in mountainous areas and are extremely lacking in loess. Although other sources of soil in other domestic mining areas are competing with agriculture to destroy vast tracts of arable land, in order to implement the principle of agriculture and strengthen workers ’and peasants’ Union, in order to give full play to the role of the existing grouting system to ensure safe production, according to local conditions to find alternative materials grouting has become an urgent issue to be addressed. According to the scientific research plan of the Ministry of Coal Industry and the instruction of Sichuan Coal Administration, Sichuan Coal Industry Research Institute of Furong Mining Bureau and Chongqing Coal Industry formed a three-in-one experimental group to carry out research on fire prevention and extinguishing of pulverized pulping of Feixianguan shale. Bureau fir CIMC South wells for testing.
