针对某矿地压活动现象明显、巷道和采场冒落时有发生的状况，进行了地压相似材料模型试验，以求对地压问题的具体认识，介绍了模型的制作和试验情况，并根据实验结果，分析了开采过程中围岩应力的变化规律以及岩移变化趋势，从而为制订矿山开采和地压控制措施提供了重要的依据。 Aiming at the obvious phenomenon of ground pressure in a mine and the occurrence of roadway and stope when the roadway and stope collapsed, a similar material model test of ground pressure was carried out in order to get a concrete understanding of the problem of ground pressure and introduced the making and testing of the model. According to the experimental results, the change law of surrounding rock stress and the trend of rock movement during the mining process are analyzed, which provides an important basis for the development of mine exploitation and ground pressure control measures.
