摘要
Abstract
In order to effectively solve the problem of gas over-limit in alpine coal mine,taking 50230 working face as the research object,the design scheme of high-angle drilling is determined based on theoretical analysis and calculation.Through field measurement,the gas drainage effects and engineering benefits of long-distance directional high-angle drilling and directional bedding drilling are compared.The results show that the unit extraction capacity of directional high-angle drilling is more significant than that of bedding drilling,which increases by 1.3～2.1 times,reflects better social and economic benefits,and ensures the safe and efficient production of the mine.关键词
