某铁矿矿体厚度大,品位高,资源开采条件好,但受到采矿方法的限制,导致生产能力低下,成本高,无法达到设计的生产规模。通过对该矿的开采技术条件的调查研究,根据岩石流变特性,提出了分区分段充填采矿及强采强充的观点,进而提出了较为新颖的小空间“品”字形高效分段充填采矿法。该采矿法具有盘区“品”字形上向分段回采顺序、分区强采强充、遥控铲运机出矿等特点,成功实现了低成本和安全、高效开采。
The thickness of a certain iron ore body is large and its grade is high. The condition of resource exploitation is good, but it is limited by the mining method, resulting in low production capacity and high cost, failing to reach the designed production scale. According to the investigation and research of the technical conditions of the mine, according to the rheological characteristics of the rock, the author puts forward the viewpoint of sub-area and sub-section filling and strong strong charge, and then puts forward a novel and novel space Filling mining method. The mining law has the panel “product ” glyph on the order to sub-mining, sub-district strong, remote control scraper out of ore and other characteristics, the successful realization of the low-cost and safe, efficient mining.
