Determination of length and productivity of a mining block
Abstract
The labor costs of the main and auxiliary mining processes depend on the number of excavators on the ledge, which determines the length of the blocks and the intensity of the front movement. Under the length of the block is meant the length of the front of work per excavator, which provides independent and productive operation of mining transportation equipment. The length of the block is determined by the conditions of rational technology of adjacent tsroizvodstvennyh processes - loosening, loading and transportation - in accordance with the “Standard projects of development systems and transportation at quarries." When designing the length of the block is taken according to practice, norms or standard projects ...
