Method and device for determining mining boundary of open pit coal mine
The invention discloses a method and a device for determining the mining boundary of an open pit coal mine. The method comprises the following steps: acquiring a first stability coefficient of a first slope at different engineering positions in each section of a mining area; the first slope with the first stability coefficient not smaller than the safety reserve coefficient is determined as a target first slope; determining an engineering position corresponding to the target first slope with the boundary stripping ratio not greater than the economic stripping ratio as an initial mining boundary; the initial mining boundary is locally adjusted, and a second stability coefficient of a second slope in the adjusted initial mining boundary is obtained; performing morphological optimization on the second side slope with the second stability coefficient smaller than the safety reserve coefficient to obtain a morphological optimization result of the second side slope; and determining a final mining state based on the morphological optimization result, the economic stripping ratio and the resource recovery rate. According to the method, the technical problem that resource waste is easily caused due to the fact that slope stability and mining cost are not comprehensively considered when mining boundary delineation is carried out in related technologies is solved.
本发明公开了一种露天煤矿的开采境界确定方法及装置。其中，该方法包括：获取开采区域的各个剖面中不同工程位置处第一边坡的第一稳定系数；确定第一稳定系数不小于安全储备系数的第一边坡为目标第一边坡；确定境界剥采比不大于经济剥采比的目标第一边坡对应的工程位置为初始开采境界；对初始开采境界进行局部调整，并获取调整后的初始开采境界中第二边坡的第二稳定系数；对第二稳定系数小于安全储备系数的第二边坡进行形态优化，得到对第二边坡的形态优化结果；基于形态优化结果、经济剥采比和资源回收率确定最终开采境界。本发明解决了相关技术中在进行开采境界圈定时，没有综合考虑边坡稳定性和开采成本，容易导致资源浪费的技术问题。
