欧洲所用大部分框架锯有效锯切尺寸为3×2×1.5米,欧洲的矿山已经适应了这种框架锯的工作标准。而在印度,从欧洲引进的以欧洲技术条件制造的框架锯,其能力得不到充分的发挥。其原因:(1)目前印度石材矿山开采较为普遍地使用的是风钻与火药,采出荒料块度小;(2)即使开采出大块荒料(3×1.5×1.5米),印度大部分矿山也无法吊装,无法运输(往返于矿山与加工厂的卡车载重量只有10吨);(3)印度的石材性质变化很大。例如磨损系数,大理石为0.8
Most of the frame saws used in Europe saw an effective sawing dimension of 3 by 2 by 1.5 meters, and mines in Europe have adapted to the operating standards of such frame saws. In India, however, the capabilities of the framework saws, introduced from Europe and manufactured under European technological conditions, were not fully realized. The reasons are as follows: (1) At present, stone mines and gunpowder are commonly used in the mining of Indian stone mines, and blocks with small blocks are small. (2) Even if large block blocks (3 × 1.5 × 1.5 m) are mined, Some mines can not be hoisted and can not be transported (truckloads to and from mines and processing plants are only 10 tons); (3) The nature of the stone in India varies greatly. For example, wear coefficient, marble is 0.8
