摘要
为了研究支承压力在底板的传递规律及底板附加应力的分布规律,在分析支承压力分布规律的基础上,运用弹性力学理论建立了底板任意一点附加应力的计算公式,结合某矿地质采矿条件,给出了底板附加应力的等值线图,并分析了底板相对固定点的附加应力与采宽、采深等开采参数的关系。
In order to study the transfer law of abutment pressure and the mining floor additional stress distribution, based on the analysis of the distribution law of abutment pressure, a calculation formula of additional stress of the mining floor is established through elasticity method, combined with the geological and mining conditions of a certain mine, the mining floor additional stress contours is presented, and analyze the relationship between mining width, mining depth and the additional stress of a related fixed point of the floor.
