The Application of Numerical Simulation in Feasibility Research of Ascending Mining

Abstract:

In order to study the feasibility of the ascending mining in Maiduoshan coal mine, the “two belts” of 6# coal should be predicting. Based on the analyzing of mine hydrogeological conditions, the three-dimensional numerical model is established by the FLAC3D, the scope of “two belts” by lower coal mining is predicted. The results shows that the fracture zone height of 6# coal less than the distance between 6# coal and 2# coal, and Maiduoshan coal mine meet the requirement of ascending mining. At the same time, combining the ratio method and balance analysis of surrouding rock, ascending mining is feasible in Maiduoshan coal mine.
