煤矿采掘工作面“5J”“4S”法过废弃石油井
|
摘要
双马煤矿井田范围内存在大量的废弃油井,这些油井由于施工年代久远,缺乏资料,不仅给矿区的设计开采带来困难,而且对于油气井邻近煤层的开采有重大的安全隐患。采掘工作面揭露油气井,存在水、火、有害气体及顶板等重大灾害隐患,严重影响到煤矿的安全开采。在采掘过程中,一旦揭露废弃油井,容易造成不可预测的安全事故。
There are a large number of abandoned oil well within the scope of the Shuangma Coal Mine,these wells had constructed for a long time,information is in deficiency,not only had brought great difficulties to the design and exploitation of the mining areas,but also the major safety hidden trouble in the mining of coal seam near the oil wells,once the mining face reveals oil and gas wells,major disasters,like water,fire,harmful gases and the roof,etc.will seriously influence the safety exploitation of coal mines,once exposed the abandoned oil well in the process of mining,unpredictable safety accidents are likely to occur.
