陕煤神南柠条塔矿业公司结合自身的实际,积极实施科技兴矿战略,先后与中国矿业科学协同创新联盟六次对接研究。决定在柠条塔煤矿井下南翼2-2煤厚煤层工作面进行“110工法”的科研及工程实施,取得了实质性的效果。1.“110工法”简介“110工法”是在工作面推采前,在胶运顺槽工作面侧顶板提前定向切顶,切断部分顶板的矿山压力传递,进而利用顶板岩层压力,利用切顶后垮落的部分顶板岩体堆砌成巷帮(有挡矸支护),原有胶运顺槽得以保留,
In accordance with its own actual conditions, Shaanxi Shennan Caitian Tower Mining Co., Ltd. actively implemented the strategy of prospering the mine by science and technology and successively conducted six docking studies with China Mining Science Collaborative Innovation Alliance. It decided to carry out the scientific research and project implementation of the “110 Method” in the coal seam of the 2-2 coal seam in the south wing of the Caitang Tower and achieved substantive results. Before the mining face is pushed forward, the top roof of the roof of the Jiao Yun Shun tank is cut in advance to cut off the pressure transmission of the top part of the mine, and then the top rock strata pressure is utilized , The use of part of the top of the collapsed roof rock pile piled into the road to help (there are pieces of rock support), the original plastic transport cistern to be retained,
