摘要
为改善某矿大倾角煤矿井下采煤安全的问题,分别对采煤参数与采煤工艺进行了优化,经现场使用,改进方案提高了的开采的安全性,使得煤层月均开采量特生 36%,回采率提升 10.99%,回采功效增加 32.8%,年产值增加1 800 万元,提高了矿区的经济效益.
Abstract
In order to improve the safety of underground coal mining in a large inclined coal mine,the mining parameters and mining technology were optimized respectively.After on-site use,the improved scheme improved the safety of mining,resulting in an average mining output of 36%per month,an increase of 10.99%in the recovery rate,an increase of 32.8%in the recovery efficiency,an increase of 18 million yuan in the annual output value,and an increase in the economic benefits of the mining area.
