本文通过不同采深岩盐溶腔稳定性相似模拟试验研究，探讨了岩盐水溶开采过程中溶腔围岩移动、破坏和应力重新分布特征。得出了溶腔上覆岩层下沉量、下沉速度和围岩中各岩层支承压力峰值集中系数及其影响范围随开采跨距和深度的变化规律，以及不同开采深度岩盐溶腔顶板极限跨距和卤井生产服务年限等。 In this paper, through similar simulation tests on the stability of salt caverns in different mining depths, the characteristics of the movement, destruction and stress redistribution of cavern surrounding rock in dissolution process of rock salt are discussed. The results show that the subsidence and sinking velocity of overburden overburden and the peak concentration factor of supporting pressure of each subterranean rock in surrounding rock vary with the variation of mining span and depth and the limit span of roof of salt rock cavern with different mining depth Distance and brine production service life and so on.
