| 摘 要： | 为了确定刘河煤矿13021工作面开采对覆岩破坏高度的影响和防砂煤柱的留设，采用实验室相似材料模拟试验，分析了13021工作面推进过程中，其上覆岩层的破坏高度的动态演化过程。通过对不同剖面的相似模拟发现，在13021工作面一次采全高平均采厚2.7 m，上覆岩层垮落带最大高度为16.1 m，模拟结果对于防砂煤柱的留设具有一定的参考价值。

| Abstract: | The similar material model test was used to study the influence law of mining of 13021 working surface of Liuhe Coal Mine to failure height of overburden rock, while the sand-proof pillar was also determined.Dynamic evolution process of the failure height of the overburden rock during mining process of 13021 working surface was analyzed.Through the different section of the similar material model test, the test results indicate that the average thickness of full-seam mining at 13021 working surface is 2.7m, and the maximum height of overlying rock caving zone is 16.1 m.The results of model test have certain of reference value for the establishment of sand-proof pillar. |
