据英国采矿杂志1990年11月号报道:位于澳大利亚新南威尔士州的葛莱特里矿开采奥德莱煤层,厚1.8~2.5m,平均2.1m,采深70~90m,顶板为泥岩。为保护地表防止塌陷,故采用短壁部分开采法,单巷短壁工作面长30m,走向长2000m,1988年以来已采完8个面。最高月产12.7万t(21天),平均日产6045t,最高周(5天)产33383t,最高班产3463t。该矿短壁综采主要设备为:
According to British Mining Magazine, November 1990, the Geletri Mine located in New South Wales, Australia, mined the Audelai coal seam, which is 1.8-2.5 m thick with an average depth of 2.1 m and a depth of 70-90 m. The roof is mudstone. To protect the surface to prevent collapse, so the use of short-wall part of the mining method, single-lane short-wall face long 30m, to the long 2000m, since 1988 has been taken eight surfaces. The highest monthly output of 127,000 t (21 days), the average daily output of 6045t, the highest week (5 days) yield 33383t, the highest class production 3463t. The mine short-wall fully mechanized mining equipment:
