一、標準炮眼排列的重要性在鑛山企業中,提高坑道掘進傘,保証超过國家定额,以達到降低成本,提高勞動生產率,給國家積累大量基金的目的,是採鑛作業的重要任務。在構成每个單元掘進作業時,不僅要根據不同种類和性質的岩石或矿石,决定掘進体型,炮眼數目及打眼方法等,同時也必須依靠炸藥的能量,來破壞岩石抗力,这就是構成掘進工作中最基本的鑿岩爆破工作。岩石或鑛石,根據其含有矿物成份和構造上物理机械性質的不同,其鑿岩作業的鑿岩性、爆破工作的爆破性和採鑛作業的採掘性也各個不同,这些條件直接影响着生產工作的進
First, the importance of the standard hole arrangement In mining enterprises, to improve tunneling umbrella, to ensure that more than the national quota in order to reduce costs and improve labor productivity, the purpose of accumulating a large number of funds for the country is an important task of mining operations. In forming each unit of tunneling operations, not only according to different types and nature of the rock or ore, determine the size of the tunneling, the number of eyelets and methods of drilling, but also must rely on the energy of explosives, to destroy the rock resistance, which is forming tunneling Work in the most basic blasting work. Rocks or ores, depending on their mineral composition and the physical and mechanical properties of the structure, have different rock drilling performance, blasting performance and mining operations’ mining ability. These conditions have a direct impact on the production Work into
