摘要
Bukit Asam Tbk是南苏门答腊岛Muara Enim的一家露天煤矿开采公司。在露天矿开采活动中,通过边坡稳定性分析对矿山进行评价,以制定安全的开采工艺。几种类型的边坡破坏与地质构造有关。本研究利用代表低壁区岩性的8个观测点的不连续面数据,利用扫描线方法确定了Bukit Asam Tbk X PT低壁区的滑坡类型,并确定了边坡稳定系数。研究方法主要有运动学分析、平面滑型边坡稳定性分析和楔型边坡稳定性分析。通过运动学分析,确定了X坑低壁区存在边坡相对稳定的平面型和楔型滑坡的可能性。
Potensi longsor berdasarkan analisis kinematik pada area low wall PT. Bukit Asam Tbk, site Tanjung Enim, Sumatera Selatan
PT. Bukit Asam Tbk is an open-pit coal mining company in Muara Enim, Soutgh Sumatra. In open-pit mining activities, slope stability analysis is carried out to evaluate the mine in order to create a safe mining process. Several types of slope failure are associated with geological structures. This research was conducted to identify the type of landslides in the low wall area of Pit X PT. Bukit Asam Tbk and determine the slope stability factor based on discontinuity data using the scanline method at 8 observation points that represent the lithology of the low wall area. Methods used in this research is kinematic analysis, slope stability analysis on plane slide types and wedge. Based on the kinematic analysis, it was identified that the Pit X low wall area has the potential for plane and wedge type landslides with a relatively stable slopes.
