在杰兹卡兹甘各矿采空区充填采矿法的采矿量比重约占8%。使用空场采矿法时,随着开采深度的增大,矿柱和顶板的破坏越来越多,所以要求在杰兹卡兹甘矿区各矿广泛采用充填采矿法。现在所用的充填采矿法的主要缺点是:一步骤矿房未充满和充填体未起到支承作用,因此,在开采二步骤矿房时,暴露跨度很大,引起顶板冒落,更大的危险是有可能
Mining accounts for about 8% of the mining charge in the Grizzly Gamble Mine. With the use of the opencast mining method, as the depth of mining increases, the destruction of pillars and roofs becomes more and more frequent, requiring the widespread application of the Filling and Mining Law at each mine in the Jetskazan mine. The main drawbacks of the Filling Mining Act now used are that one-step mines are underfilled and the backfill does not function as a support and as a result, there is a large exposure span in the two-step mining operation, causing the roof to fall, posing a greater risk Is possible
