投料孔施工技术及其应用

Construction Technology of Mine Surface Ground Material Feeding Borehole and Application

为了缩短麻家梁矿井建设周期,节约基建成本,满足矿井建设需要,采用钻铤孔底加压、泥浆护壁的工艺技术在地面施工投料孔。基于投料孔在矿井建设中实际应用的重要性,文章介绍了投料孔施工方法,研究了投料孔应用的经济效益、应用前景及局限性,实践表明,投料孔在矿井建设中经济效益明显,具有广阔的推广前景。

In order to reduce the mine construction period of Majialiang Mine, to save the capital construction cost and to meet the mine construction requirements, a drill collar weighting at the borehole bottom and driUing mud protected shaft wall technology was applied to the mine surface construction of the material feeding borehole. And the paper introduced the construction method of the material feeding borehole and studied the economic benefit, application prospect and limitation of the material feeding horehole. The conclusion showed that the material feeding horehole in the mine construction would have obvious economic benefits and wide promotion prospects.
