摘要
基于厚冲积层及薄基岩条件下条带开采观测数据,分析了表征空间形态的地表移动角量参数;优化了常规条带开采采动影响预测的地表移动计算参数;拟合了采用窄工作面计算方法计算的地表移动参数,用于计算非充分宽条带短壁工作面开采地表移动计算。通过实践,只要采用合理技术与设备,即使是在条带开采条件下,也能达到高产高效。
The angle dimension parameters of surface movement, tokens of space shape, are analyzed in this paper based on the observation data of strip mining under thick alluvium and thin bedrock. The surface movement parameters of routine strip mining are optimized. The surface movement parameters calculated in narrow face are fit to calculate the surface movement parameters of short-wall face of broad strip in insufficiency mining. The practice shows that high output and high efficiency may be gained even in strip mining if only rational technology and equipments are adopted.
