摘要

截至2017年3月底,长达36年的合作作业共开采出石灰石约2.48亿吨。自1994年11月以来,采用多种装置和方法对布哥山岩质边坡的力学行为进行了监测。2007年9月,一场台风带来的强降雨,在岩质边坡的某些部分造成了前所未有的明显但短期的移动,这使得三家矿业公司加强了监测,并迅速从岩质边坡中抽取地下水。为减少雨水渗入石灰岩,现正进行石坡道路铺路工程。此外,23根钢管(长80米,直径600毫米)被灌入岩石边坡,总重量约240万吨的挡土桩正在建造中,以加强无形薄弱面的阻力。

Limestone Mining and Slope Management at Mt. Buko
the end of March 2017, the 36 years long cooperative operations mined out about 248 million tonnes of limestone. The mechanical behavior of the Mt. Buko ’ s rock slope has been monitored by several kinds of devices and methods since November 1994. In September 2007, a heavy rainfall of a typhoon caused unprecedentedly distinct but short-term movements in some part of the rock slope, which made the three mining companies intensify monitoring and prompt groundwater drainage from the rock slope. In order to reduce permeation of rain into limestone, paving works of roads on the rock slope are being carried out. Moreover, twenty three steel pipes (80 m long × 600 mm in diameter) were piled into the rock slope and retaining rock piles of total weight of some 2.4 million tonnes are being constructed to reinforce the sher resistance of invisible planes of weakness.
