The System Of Prediction Evaluation On Mining Damage

Controlling and reducing damage about mankind's subsistence environment by miming, which is a cosmopolitan difficult problem that mine production safety, high production, high efficiency is facing. In our country, North china, Northeast, East china, it make a lot of mining areas become vast ocean to mine, but in the west of our country, the water of groundwater has droped by mining, and soil eroded has brought on desertification. At the same time, the mali_ gnant accidents of destruction about roads and buildings, and the inflooding mine by ground_ water to leak, which are often raise. So mankind must have a scientific development view and Strengthen controlling and administration it, or else we'll pay out heaviness cost for it. This thesis aims at this problem to empolder the system of prediction evaluation on mining damage. According to the demand of the prediction evaluation, author establishes the common-fitting model base on the probability integral by the main ideology of " mining project--movement and deformation about the rock strata overburden and surface--damage analysis of the surface buildings", and gives out the expression of dynamic movement distortion and the correlation of them by the mode of combining figure and graph. This thesis emphasisly researchs the main factors of dynamic prediction theory about calculation parameters and the choice methods, and compiles the correlation program of probability integral and dynamic datebase, and combines Wilson's theory, the program of finite element FLAC3D and the knowledge of Qian Minggao academician's key stratum theory and MapGIS communication system to study and analysis the mining damage at the mode of entirely basin and large area, and realizes much azimuths and much angle to predict and evaluate, it is a applied, convenient, controlling and administration system of prediction evaluation on mining damage in mining area.
