软煤层巷道围岩控制问题是一直以来制约煤矿开采的重大难题,具体表现为强烈的底鼓、两帮移近量较大和顶板下沉剧烈,在分析巷道支护所要遵循原则的基础上,结合新义煤矿11011工作面运输顺槽巷道支护工程实践,采用U型钢、锚索联合支护技术很好地控制了软煤层巷道的稳定,此项研究成果为解决突出软煤层巷道支护问题提供了借鉴经验。
Surrounding rock control of soft seam roadway has been a major problem restricting the coal mining all along, which is characterized by a strong bottom drum, a large amount of two gangs and a heavy roof sinking. On the basis of analyzing the principles to be followed for roadway support, The application of U-shaped steel and anchor-cable joint support technology to control the stability of roadway in soft coal seam well in 11011 working face of Xinyi coal mine, the research results provide a solution to the problem of roadway support prominent in soft coal seam Learn from experience.
