运用实测数据分析、模型试验和数学模拟方法 ,研究某倾斜煤层矿山开采过程中的沉陷和岩层移动。根据模型理论建立了相似模型 ,用 2D σ程序进行数值模拟。结果表明 ,沉陷和水平移动曲线不连续也不平滑 ,由于地质条件的影响 ,其变化是不对称的。得出沉陷参数、水平移动参数、顶部下沉量和其他用于预测地面移动的参数。这些参数值与当地采矿条件一致 ,有助于开采作业。实践证明 ,研究结果对预测地面移动和下沉有益 Using measured data analysis, model test and mathematical simulation method, the subsidence and rock movement during mining of a sloping coal seam are studied. According to the model theory, a similar model is established and the numerical simulation is carried out with 2D σ program. The results show that the subsidence and horizontal displacement curves are discontinuous and not smooth, and the variation is not symmetrical due to the geological conditions. Subsidence parameters, horizontal movement parameters, top subsidence amount, and other parameters used to predict ground movement are derived. These values ​​are consistent with the local mining conditions and are conducive to the mining operations. Practice has proved that the results of the study are good for predicting ground movement and sinking
