采场地压控制是空场采矿法开采工艺的关键环节。
In open stopes the ground above the stope will support its own weight. So the stope is shaped like a series of rooms divided by walls or supported by pillars of ore.空场回采工作面利用采场上方的岩层支撑自身的重量,所以采场被切割成一系列的由矿壁分隔或用矿柱支撑的峒室。
Combining with several years experience on open stope backfill in one time, the causes of the problems were analyzed and some technique improvements were put forward.结合某矿分段空场嗣后一次充填采矿法的多年实践,分析了充填接顶和采场脱水问题的产生原因,详细叙述了控制空场嗣后一次充填质量的改进技术。
