摘要
煤炭和水都是人类生存和发展的宝贵资源.兖州矿区厚松散层下近风化带的煤炭开采一方面受到第四系下组水的威胁,同时还涉及到第四系下组水资源的合理保护问题.本文以兖州市杨庄矿为例,建立了GIS数据库和图形库,通过GIS多因素拟合建立了近风化带覆岩采动破坏"两带"高度的预计模型,提出了考虑保护层的开采上限GIS决策模式,用于保水条件下的安全煤柱留设设计.
Coal and water are both priceless resources for humanity. But it is a flood that the water in the bottom of Q4 come into workface and it's a difficulty to preserve such water resources during mining under thick unconsolidated water-bearing strata adjacent to the weathered zone. Firstly a graph and data base was set up according to the material of Yangzhuang Coal Mine. Then several major factors of geology and mining were selected and a GIS prediction model was established for overburden failure. The protective layer of water insulation and the upper mining level were discussed and judged by using GIS decision model. Therefore, safety pillars can be designed.
