基于Mathews稳定图法的采场暴露面积确定

Determination on the Exposure Area in Stope Based on Mathews Stability Graphic Method

采场暴露面积的确定直接影响采场结构参数的合理布置,采用阶段空场嗣后充填采矿法时,需要同时讨论采场顶板和充填体侧帮的暴露面积。采用Mathews稳定图法对采场的暴露面积进行了计算,并且与国内外相似的矿山进行比较,最终确定了采场的合理暴露面积,为确保矿山安全生产提供参考。

Determination of the stope exposed area can influence the rational arrangement of the stope structure parameter directly. It is necessary to discuss the exposed area of the stope roof and lateral wall of backfill when the back-filling mining afterwards open-pit method is used. The Mathews stability graphic method is used to calculate the stope exposed area and compared with the situations of the similar mines domestic and overseas. The reasonable exposed area is determined ultimately so as to provide refer- ence for ensuring the mine safety production.
