摘要
煤田火烧区的存在,给勘探、建井、开矿均带来一定的危害。重点论述新疆煤田火烧区的特征、危害和主要形成因素,经过各种勘探方法的对比,选用地面物探方法(磁法和自然电场法)查清了煤层火烧区的分布范围和煤层地下燃烧状态。物探成果资料经钻孔验证技术效果良好,根据煤层高温燃烧区定期观测剖面测定结果,对新疆煤田火烧区储量的损失作了科学的推算。对煤田高温燃烧区灭火方法及灭火工程的验收程序效果提出了合理化建议。
The present of coalmine underground combustion area brings about certain hazards in exploration, mine construction and mining. The paper emphasizes on underground combustion area features, hazards and main geneses. With reference to various exploration methods, we selected surface geophysical prospecting (magnetic method and natural field method) to ascertain underground combustion distribution range and underground coal seam combustion state. After borehole proving, the technical effects of geophysical prospecting results are all right. The paper made a scientific calculation for reserve decrement due to underground combustion according to combustion area periodic observed profile results. Put forward rationalization proposals on fire-fighting methods and a fire-fighting engineering acceptance procedure.
