采场地压控制
ground control of stope
ca℃泊门9 diya kongZhi采场地压控制(ground eontrol of stope)为使采场周围岩体在回来期间不因次生应力作用而破坏或不按预期形式破坏而采取的措施。采场是进行回采的或回采后形成的敞空空间或堆积着落下矿岩或充填材料的空间。采场的形成使其周围岩体的原始应力改变.而形成次生应力场。其范围就是采场围岩应力重新调整的范围。采场围岩所受的力和采场围岩施加十采场中支撑体的力都叫做采场地压。采场地压引起围岩或支撑体明显变化，叫做采场地压显现或采场地压活动采场地压控制，要考虑矿柱尺寸计算.采场围岩加固，充填体作用和采空区处理。 为使回采工作顺利进行，采用自然支撑、人工支撑和崩落等方法控制采场地压 川自然支撑使留在采场中的各种矿柱具有合适的尺寸一和间距，并选取合适的采场顶板暴露面积，以使采场围岩中的次生应力不超过围岩强度极限使用空场采矿法时随回采工_作发展不断遗留采空区，从而使采空区围岩中的次生应力不断叠加。为了防止出现大规模地压活动，应采取适当方法及时处理采空区。 (2)人工支撑为防止在回采过程中，采场周围岩体因自身强度不够或因受构造影响而变形或片落，针-对不同情况.采取各种人工加固和支撑围岩的措施。通常用锚杆、锚索和注浆加固采场周围岩体，或用充填材料、立柱、方框支架等支撑采场周围岩体 〔3)崩落随回采_I二作进行强制或自然崩落采场周l%l岩体.使回采_l二作空间周围岩体中应力降低或使落矿费用减少 (郑永学)
