摘要
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 。
The mining subsidence and strata movement of N coal mine area is investigated by means of analysis of practical measurement data, modeling experiment and numeric analyzing. Similitude model is established by modeling theory, and numeric analysis is implemented by 2D σ program. The results show that the subsidence curve and horizontal movement curve are not continuous and smooth, but are unsymmetrical with some variation caused by geological conditions. The subsidence parameter, horizontal movement parameter, top subsidence extent and other parameters used to predict ground movement are obtained. These parameters are consonant with the practical values of local mining conditions and helpful to mining engineering. It has been proven by practice that the research achievements are beneficial to ground movement control and subsidence disaster prediction.
