针对“三软”厚煤层具体情况,运用相似模拟技术,模拟采场受到采动影响后的变化状态,得到采场工作面前方支承压力分布范围,采场的应力分布情况,上覆岩层的破坏和运移趋向,并将实验结果与现场检测结果进行比较,显示两者吻合较好。该实验能够对采场上覆岩层分布进行很好的模拟,对安全生产具有一定的参考价值和指导意义。 According to the actual conditions of thick coal seam with “three soft” thicknesses, similar simulation technology was used to simulate the changing state of stope affected by mining. The distribution of supporting pressure in front of working face and the stress distribution in stope were obtained. Of the destruction and migration trends, and the experimental results and field test results were compared, showing good agreement between the two. This experiment can simulate the distribution of stratum overlying strata and has certain reference value and guiding significance for safety production.
