通过相似材料模型实验,对“三软”煤层上覆岩层的移动破坏规律进行了研究。结果表明:“三软”煤层的上覆岩层具有从下往上分层破坏的特性;上覆岩层距煤层越近,下沉量越大,距煤层越远,下沉量越小。 Through the experiment of similar material model, the movement and failure of overlying strata on the “three soft” coal seam are studied. The results show that the overlying strata in the “three soft” seam have the characteristics of stratification from bottom to top; the overlying strata are closer to the coal seam, the larger the subsidence and the farther away from the coal seam, the smaller the subsidence.
