Research and Analysis on the Gas Drainage Optimization measures in Qian Jiaying Mine

Xu Shen, Guo Li-wen, Zhang Jia-yong ( Hebei United University, Hebei Tangshan 063009 )

Abstract:

After analyzing Qianjiaying mine gas-drainage result. To solve problems of the gas-drainage and com-bined with the main source of combined coalface gas, which proposed the method of pre-pumped parallel gas drill-ing. And it proposed the method of excavating roadway when drainage gas in the heading face at the same time. Based on the old methods that include gas-drainage in the gob and upper corner, which proposed the method of installing pneumatic fan with the wind net, to dilute the gas in the upper corner. Used second hole sealing process in order to improve the amount of gas extraction that solved the problem of gas drainage in Qian Jiaying Mine.
