山脚树矿机械造穴增透技术的应用研究
Application research on mechanical hole-making and transparency enhancement technology in Shanjiaoshu Mine
摘要
Abstract
Regarding the complex situation of low permeability,high gas content,high pressure,and inclined characteristics of the coal seam in Shanshanshu Mine,taking the No.221015 transportation roadway of No.10 coal seam as a research case,and the mechanical hole-making and transparency enhancement technology for gas control was adopted.Through the analysis of the coal seam permeability and gas extraction effect after mechanical hole-making,the results show that this technology has demonstrated significant anti permeabil-ity and extraction effects in low permeability and hard protruding coal seams.It can not only significantly improve the permeability of coal seams in the affected area,but also effectively reduce the pressure inside the coal body,playing a significant role in reducing gas power,thereby significantly improving the overall effect and efficiency of gas extraction.关键词
