本文通过相似材料模型试验探讨了条带法开采中条带煤柱的支撑状态及覆岩和地表移动问题。作者发现条带法开采中覆岩下沉量随深度的增大而减小等与长壁式开采覆岩移动不同的特征及其他一些重要规律。上述研究对探讨条带法开采的机理和效果具有一定的理论价值和实用意义。
In this paper, the support state of strip coal pillar in strip mining and the problem of overlying strata and surface movement are discussed through similar material model tests. The authors found that the subsidence of overlying strata in the strip mining method is different from that of the overlying strata in longwall mining due to the decrease of depth, and some other important laws. The above research has certain theoretical value and practical significance for exploring the mechanism and effect of strip mining.
