突出危险煤层提高机掘工作面掘进速度试验研究
Experiment Study of Improving Advancing Speed of Mechanical Heading Face in the Seam with Outburst
摘要
Abstract
Dashucun coal mine is a high gas and gas outburst mine. Gas outburst is quite serious at the working face, It is proposed the method of hydraulic loose drillings and draining drillings working together to reduce the risk of gas outburst, and raises the speed of ad- vance rate of working face. Gas release effect has been changed better obviously In the hydraulic fraeturingg process. And gas density elevates rapidly, along with the irrigation process. The gas density comes down gradually and keep steady with the end of the process. Compared with the method before without hydraulic fracturing measure , the gas density has been reduced obviously. The experiment effect is good at Dashueun coal mine for the good choice of parameter. The average footage enhances 50% , from 120 - 140 meters per month to the approximately 200 meters per month.关键词
