In order to define a mutual disturbance range between the upper and lower ore belts of a copper-gold mine during 8-year co-mining period, a deformation law of stratum by natural caving mining method is summarized based on the characteristics of stratum movement and deformation induced by mining. Combined with the actual mining technologies on site, a law of rock movement is explored for the lower ore belt by adopting engineering analogy method, theoretical calculation method and numerical simulation method, and the critical mining-induced disturbance range is defined to ensure safe mining of the upper ore belt, which provides a basis for the planning and layout for the mining of the lower ore belt. It is found that for safe mining of the upper ore belt, the lower ore belt should have security pillars of about 550 m along the strike, with the minimum angle of stratum movement within the range from 70° to 73.3°.

为了界定某铜金矿上、下部矿带8年共采期间的相互扰动范围，从开采过程中诱发的岩层移动变形特征出发，对自然崩落法开采的岩层变形规律进行了总结，进一步结合现场实际开采技术条件，采用工程类比法、理论计算法、数值模拟法对下部矿带岩移规律进行了研究，最终界定了确保上部矿带安全开采的临界采动影响范围，为下部矿带开采规划与布局提供依据。结果表明，上部矿带安全开采所需的下部矿带保安矿柱沿走向约550 m、最小岩层移动角70°~73.3°。
