随着杰兹卡兹甘矿床进入深部开采(300米水平及其以下),与开采盘区内房间矿柱和盘区矿柱保持稳定状态时间有关的问题越来越显得突出。时间因素对矿柱应力变形状态的影响取决于破坏过程的强烈程度,而后者又依赖于岩石的流变性质。叶尔札诺夫和萨吉诺夫等人认为,岩石裂缝的扩展是变形造成的,而且由于蠕变使 As the Zezkazgan deposit enters deep mining (at 300 meters and below), issues related to the time it takes to stabilize room pillars and plate pillars in the mining area are becoming increasingly prominent. The influence of time factor on the stress and deformation state of pillars depends on the intensity of the destruction process, which in turn depends on the rheological properties of the rock. Yerzhanov and Saginov and others believe that the expansion of rock cracks is caused by deformation, and because of creep
