石材传统开采法,一般从上而下,逐层采荒,原地切割整形,机械起吊装车和清方排渣。这种方式矿山基建工程量大,包括:上山公路,顶部土石方剥离工程,因而基建工程时间长、投资大、机械效率低。又由于从上而下的采荒方式,难免存在着严重压矿造成矿体浪费。 Stone traditional mining method, generally from top to bottom, layer by layer wasteland, cutting and shaping in situ, lifting machinery loading and cleaning slag discharge. In this way, the amount of infrastructural projects in mines is large, including: the uphill road and the stripping of earthwork at the top, resulting in a long time for infrastructure construction, large investment and low mechanical efficiency. Owing to the way of top-down mining, it is inevitable that there will be serious ore mines causing the waste of ore bodies.
