煤矿掘进巷道锚杆支护技术应用研究

Research on Application of Bolt Support Technology in Coal Mine Roadway

随着国家对能源需求的增大,煤矿产量也略有增大,因而大采高和综放技术得到广泛推广使用,全国各地煤矿矿井出现了煤巷,而煤巷相比岩巷较为软弱,支护较为困难。因此,为了顺应机械化、大采高煤层的发展,软弱顶板煤层支护技术的改革非常必要。本文以某煤矿2#煤层支护为例,对软弱顶板的支护技术进行了研究,望能够为其他矿区的软弱顶板的支护提供借鉴。

With the increasing demand for energy in our country, the output of coal mines has also increased slightly. Therefore, large mining height and fully mechanized caving technology have been widely used. Coal roadways have appeared in coal mines all over the country. Compared with rock roadways, coal roadways are weaker and more difficult to support. Therefore, in order to conform to the development of mechanization and large mining height coal seam, it is very necessary to reform the supporting technology of soft roof coal seam. Taking the support of 2 # coal seam in a coal mine as an example, this paper studies the support technology of soft roof, hoping to provide reference for the support of soft roof in other mining areas.
