根据采场围岩控制原则、垮落带岩层的判别式、裂隙带老顶在触矸处的下沉量计算式和移动支承压力与采深的关系, 分析了采深对采场矿压显现不同参数的影响, 并通过实测加以验证. 根据岩性随采深的变化, 讨论了深井采场可能出现的冒顶事故, 并提出了相应的控制对策.认为采深对矿压显现的影响在采场支护方面不明显, 而煤壁片帮将随采深增加而加剧; 深部围岩逐渐变碎, 强度有所降低; 深部采场应加强对漏垮型冒顶事故的防治, 把顶板护好.
According to the principle of surrounding rock control in stope, the discriminant of rock strata in collapsed zone, the calculation formula of sinking amount of old roof in gangue zone and the relationship between pressure and mining support depth, the influence of mining depth on stope pressure was analyzed The influence of different parameters, and through the test to be verified. According to the change of lithology with mining depth, the possible roof fall accident in deep stope is discussed and the corresponding control measures are put forward. It is considered that the influence of mining depth on the occurrence of mine pressure is not obvious in the stope support, while the coal wall slab will aggravate with the increase of mining depth; the deep surrounding rock gradually crumbles and the strength is reduced; the deep stope should strengthen the leakage Collapse roof fall prevention and control, the roof protection.
