我矿氧化矿设计为底盘漏斗崩落采矿法,因其矿岩破碎,漏斗喇叭口只能在采场大爆破时一并放炮形成,过去一直采用相似估计法验收其工程量,为此,很难检测各凿岩参数在爆破之后满足设计要求之程度,乃至形成部分斗井爆破之后仍未扩开的现象。鉴于上述情况,笔者根据实地工作体会,对扩漏工程中的眼数、眼深、倾角和圈间距等用数学方法的导示公式,进行扩漏工程质量的验收,取得了很好效果,保证了扩漏质量,现简述如后。
Mine ore oxidant designed for the chassis funnel caving mining method, because of its broken ore, funnel bell mouth blasting can only be formed in the stope together with blasting, the past has been using the similar estimation method to accept the amount of the project, for which it is difficult Detection of the rock parameters in blasting to meet the design requirements of the degree, and even after the formation of part of the bucket well blasting has not yet expanded phenomenon. In view of the above, the author based on field work experience, the number of eyes in the expansion project, the depth of the eyes, the angle and the distance between the circle and other mathematical methods used to formulate the leakage of the quality of the project acceptance, and achieved good results, to ensure The leakage of quality, is now outlined as follows.
