山区地下煤层开采引起的地表移动和变形情况十分复杂,采动坡体的稳定性不仅跟地质采矿条件及覆盖岩性质有关,还跟采动程度、地形地貌、坡体形态、岩(土)性质、浅层构造等因素有关,因而,山区采动坡体稳定性的预测难度很大。本文在分析山区采动滑坡诱因、现有的山区采动坡体监测技术及坡体稳定性分析的基础上,提出构建基于GIS的山区采动滑坡预报系统,从而实现矿区绿色开采及灾害及早防治。
Ground movement and deformation caused by underground coal exploitation is very complex in the mountainous area. Slope stability is associated with the geological and mining conditions, the nature of cover rocks, the extent of mining, local terrain and physiognomy, the shape of the slope, the characters of the rock (land), and the shallow structure, etc. Thus the mountainous slope stability prediction is very difficult. The incentives of landside, the existing surveying technique and the analytic method to slope stability of the mountainous mining area are analyzed first, then how to design the landside forecasting system based on GIS is suggested in this paper, this system can advance green mining and prevent mine disasters as soon as possible.
