摘要:
为了研究空场法采空区稳定性,确定特定形态采空区稳定时间,以H-K体作为岩体本构模型,对矿柱流变引起的顶板沉降变形进行了计算分析,根据顶板边界破坏条件,将空区顶板沉降过程划分为3个阶段并分别求解了各阶段持续时间,并对尚旺庄石膏矿灾害事故进行了计算验证,结果表明,计算结果与实际失稳时间吻合良好。所得结论可为稳定空区提供稳定性评估及稳定时间预测依据,或指导老空区进行安全有效的顶板监测工作,最大化节约矿山在顶板监测工作中投入的人力、物力。
Abstract:
In order to study the stability of goaf mined by open stope method, and determine the stable time of goaf with specific morphology, taking H-K body as the constitutive model of rock, the settlement and deformation of roof caused by the rheological property of pillars were calculated and analyzed. Based on the boundary failure conditions of roof, the settlement process of roof in goaf was divided into three stages, and the lasting time of each stage was solved out. The calculation verification was conducted on the accident of Shangwangzhuang gypsum mine. It showed that the calculation results fitted well with the practical failure time. The results can provide the basis for goaf stability evaluation and stable time estimating, or guide to conduct monitoring work of roof in old goaf safely and efficiently, and save manpower and material resources putting into the roof monitoring work as much as possible.
