Mine goaf water static water accumulation amount estimation method based on three-dimensional modeling

The invention discloses a three-dimensional modeling-based mine goaf water static water accumulation amount estimation method, and belongs to the technical field of coal mining safety. According to the method, a three-dimensional grid modeling mode is adopted to accurately describe the three-dimensional spatial form of the goaf ponding according to a goaf water enrichment rule, then a complex trapezoidal calculus formula is adopted to estimate the volume of the goaf water in the spatial form, and finally an inverse algorithm is adopted to calculate the water filling coefficient, so that the defect that the calculation error of a traditional goaf water ponding amount calculation method is large is overcome. 本发明公开了一种基于三维建模的矿井老空水静态积水量估算方法，属于煤矿开采安全技术领域；本申请方法根据老空水富集规律采用三维网格化建模的方式精准刻画老空积水三维空间形态，然后采用复化梯形微积分公式估算空间形态老空水体积，最后采用反算法计算充水系数，以弥补老空水积水量传统方法计算误差较大的缺陷。
