摘要
为定量化预测矿井巷道突(透)水的蔓延过程,科学地解释突(透)水在矿井巷道中的蔓延规律,提出了基于SWMM建立矿井巷道突(透)水蔓延模型并实现定量化计算的方法。对模拟方法、参数选取进行分析,构建适用于巷道计算的SWMM模型,并通过分析矿井充水条件、设置合理的边界条件,进行矿井巷道突(透)水蔓延过程的动态预测。以河北蔚县北阳庄矿井为例,实现了矿井巷道突(透)水蔓延过程的动态预测。结果表明:利用基于SWMM构建的突(透)水蔓延模型可以计算得到任意空间位置、任意时间的水深、流量数据,并实现巷道突(透)水蔓延过程的可视化。
In order to quantitatively forecast the spreading process of inrushing water in mine roadway and scientifically explain the rule of water bursting spread in roadway,a water spread model is proposed based on SWMM. The simulation method and parameter selection are analyzed to construct a SWMM model. Based on the data of conditions for filling water,the boundary conditions were assigned,and the model is resolved. The coal mine case of Beiyangzhuang in northwest Hebei Province is selected as the study area. The water spread in Beiyangzhuang Coal Mine is represented. Hence,based on water spreading model established by SWMM in mine roadway,water depth and flow of each position at each time can be obtained,as well as the visualization of the water spreading process in roadway.
