摘　　要：文章通过对硝井水溶开采矿层上溶速度过快的问题进行针对性研究,建立了油垫法开采模式,通过多年来的实践与探索,确定油垫工艺可以减缓水溶矿层上溶速度,相对加大侧溶,控制溶腔形态,有效提高矿产资源采收率,延长井组服务年限,也证实了油垫法开采的可行性。Mining seam based on the well water soluble nitrate solution too fast on the targeted research,oil and mining mode mat method is set up,through years of practice and exploration,to confirm the oil pad technology can slow down the water soluble seam on dissolving speed,relatively increase side to dissolve,and control of the cavity shape,effectively improve mineral resource recovery,service life well group,also confirmed the feasibility of the method of mining oil pad.

关 键 词：油垫工艺 采收率 上溶速度 溶腔 水溶开采
