摘要
针对我国煤矿日益严重的顶板涌(突)水问题,提出了解决煤层顶板涌(突)水条件定量评价的“三图-双预测法”,并在开滦荆各庄矿和东欢坨矿得到成功的应用.在对荆各庄矿煤9顶板直接充水含水层的富水性和开采顶板冒落的安全性进行分区研究的基础上,运用多源地学信息复合叠加原理,提出了煤9顶板冒落涌(突)水条件综合分区的划分方案.最后运用国际先进的VisualModflow专业软件对即将回采的2099,2393两工作面的工程涌水量和顶板直接充水含水层的采前预疏放方案进行了动态预测.
In the light of more and more serious water bursting problems on roof of coal layers, a new method which is called as “three maps two predictions” is put forward firstly. The method has been successfully applied to solve the roof water bursting problems at Jinggezhuang and Donghuantuo Coal Mine in Kailuan. On basis of division researchs for aquifer water enrichment and inbreak in safety of coal seam No 9 in Jinggezhuang Coal Mine, the final comprehensive division program of water bursting conditions is presented through overlapping of multiple source geo information. Finally, both water bursting inflows of mining faces 2099 and 2393 and beforehand dewatering program for the water filling aquifer are predicted by utilizing advanced professional software Visual Modflow.
