缓倾斜中厚矿体采矿方法现状及发展趋势

缓倾斜中厚矿体的开采是一个世界采矿技术难题。对国外缓倾斜中厚矿体开采现状进行了介绍，国外矿山由于矿床规模大，矿石价值较高，拥有较强的经济实力和技术力量，主要采用房柱法和充填法；我国的经济和技术基础较薄弱，缺少引进设备的资金和应用的技术基础，因此在缓倾斜矿体开采中，以房柱法和空场法为主，装备水平较落后，低投入、低效率、高贫损。对缓倾斜中厚矿体采矿方法发展趋势进行了分析。

Status Quo of Mining Methods for Gently Inclined Medium-Thick Orebodies and Their Development Trend

The mining of gently inclined medium-thick orebodies is a world-wide technical challenge. The statue quo of the mining of gently inclined medium-thick orebodies in foreign countries is presented. As foreign mines generally have large deposits with high value ores, and possess strong economic power and technical capacity, room- pillar-filling methods are mainly used there. As China has a comparatively weak economic and technical basis,and lacks the fund and technical basis for the equipment introduction and application. Therefore, room-pillar- open stope method is mainly used in mining gently dipping medium-thick orebodies, which is characterized by backward equipment, low input, low efficiency and high dilution and loss. The development trend of the mining method for gently dipping medium-thick Orebodies is forecasted.
