峒室水溶采矿法在四川川西钙芒硝矿山被普遍采用。川西钙芒硝矿床一般较平缓，但特殊的矿段也有倾角较陡的，可大于20°。彭山矿段0＃勘探线西部就属于此种情况。一些芒硝矿水溶采矿时，采用下山布置；对彭山矿来说，由于矿层倾角大，采用下山布置时巷道施工难度大，所以布置成 Tantalum water-soluble mining method in Sichuan Chuanxi glauberite mine is widely used. Glauberite deposits are generally gentle in western Sichuan, but special ore sections have steeper dip angles, which can be larger than 20 °. Pengshan section 0 # exploration of the western part of this case. Some Glauber mine water mining, the use of down the mountain layout; Pengshan mine, due to the seam angle is large, the use of downhill layout of roadway construction is difficult, so arranged
