摘要
煤矿开采沉陷预测受多参数影响下,沉陷预测效果可视性较差,引入三维虚拟仿真技术进行煤矿开采沉陷预测。构建煤矿开采沉陷复杂模型,计算沉降区域的三维关键点坐标,再选取煤矿开采沉陷约束指标,通过模糊权重方法计算沉陷指标权重数值,并判断开采沉陷预测等级,实现了煤矿开采沉陷预测。运用MATLAB仿真软件,模型进行三维模拟应用。仿真实验数据显示:模型对煤矿开采沉陷预测等级误差为0.63%,煤矿开采沉陷预测效果值高于最低限值,充分证实了方法的可行性。
Under the influence of multiple parameters,the visibility of coal mining subsidence prediction is poor.3D virtual simulation technology is introduced to predict coal mining subsidence.The complex model of coal mining subsidence is constructed,the 3D virtual key point coordinates of the subsidence area are calculated,the constraint indexes of coal mining subsidence are selected,the weight value of the subsidence index is calculated by the fuzzy weight method,and the prediction grade of mining subsidence is judged to realize the prediction of coal mining subsidence.The three-dimensional simulation application of the model is carried out by using MATLAB simulation software.The simulation experimental data show that the prediction grade error of the model for coal mining subsidence is 0.63%,and the prediction effect value of coal mining subsidence is higher than the minimum limit,which fully proves the feasibility of the method.
