Drilling and Filling Construction Technology of Zhouyuanshan Coal Mine Goaf Group in Hunan Province
It will produce coal gangue,waste rock,tailings,etc in the process of mineral resources development and utilization,and large quantities of mine waste piled up on the surface can easily induce debris flows and tailings dam failures.And a large number of underground goafs generated by mining deposits are easy to induce geological disasters such as collapse,mine earthquake,landslide,mine water inrush and so on.The instability of the mine goaf group has become one of the main sources of danger for mine safety production.Combined with an engineering practice,this paper not only analyzed and studied the geological characteristics of the mining area and the drillability of its rock formation,but also discussed the technical methods of drilling hole formation and filling construction in the mine goaf group.In addition,it also obtained the ratio of tailing paste in the tailing sand filling system through laboratory tests.Using the information technology and method,a three-dimensional vectorization and visualization model of the underground roadway and its goaf group in the mining area was established,which has guiding significance for the drilling and forming of holes.
