摘要
近些年,全国煤矿安全形势较为严峻,各类安全事故频发,其中采空区、老窑透水事故发生较多。1930煤矿于1988年投产至今,已回采近23年,矿井开采水平经过两次延深,垂深达到150余米。矿井现回采的36211综采工作面受上部35211采空区积水威胁,为确保36211工作面回采安全,需对35211采空区积水进行探放工作。经过研究决定采用远距离深孔探、放的方式排放采空区积水,消除其对回采工作面的威胁。通过对5#煤层采空区积水量估算、探放地总选择及钻孔参数设计,顺利完成探放水工作,为矿井在今后开采深部煤层群时实施探放水工作提供了宝贵经验。
In recent years, the national coal mine safety situation is more severe, frequent all types of acci- dents, which mined-out area, the old kiln flooding incidents more. 1930 coal production in 1988, there have been no recovery of nearly 23 years, twice the level of the extension of mining depth, vertical depth of 150 meters. Recovery of 36 211 mine is fully mechanized coal face by the upper part of 35211 goal water threat, to ensure safe mining face 36211, 35211 to be mined -out area on the water to explore the place of work. After discussion decided to ex- plore the use of remote deep hole, put the way emissions goaf water, to eliminate the threat of mining face. After a rigorous calculation, rational design, well - organized , successful completion of the exploration drainage work for the deep mine coal seams mined in the future when the implementation of the exploration group has provided valuable ex- perience in drainage work.
