【摘要】：程潮铁矿在生产实际中面临平均块度过大、大块率和生产成本过高的问题,结合程潮铁矿的生产实际对KUZ-RAM模型进行等效变换并引入系数α、β进行修正得出了适用于程潮铁矿的平均块度X、均匀性系数n以及大块率Y的计算公式,在生产实际中检验了正确性,为后期计算提供了依据。利用等效变换和修正后的KUZ-RAM模型建立了与孔间距a、排距b、炸药单耗q有关的采场生产成本C的数学模型,并利用MATLAB计算机软件对采场生产成本C的数学模型进行了优化分析,得出了采场生产成本最小时的最优爆破参数为孔间距a=1 m,排距b=2.4 m,炸药单耗q=1.52 kg/m~3,最优的采场生产成本为32.5元/t,比原采场生产成本节约2.64元/t,平均块度为41.4 cm,大块率为10.5%,大块率和平均块度在合理范围,为矿山生产提供依据。
[Abstract]:Chengchao Iron Mine is faced with the problems of large average block, too high bulk rate and high production cost in production practice. Combining the actual production of Chengchao Iron Mine, the KUZ-RAM model is transformed equivalent and the coefficient 伪 is introduced. A formula for calculating average block size, uniformity coefficient n and bulk ratio Y of Chengchao Iron Mine is obtained by modifying 尾, which is proved to be correct in production practice and provides a basis for later calculation. Based on the equivalent transformation and the modified KUZ-RAM model, the mathematical model of stope production cost C related to hole spacing a, row distance b and explosive unit consumption Q is established. The mathematical model of stope production cost C is optimized by using MATLAB software. The optimum blasting parameters when the production cost of stope is minimum are as follows: hole spacing 1 m, row distance 2. 4 m, explosive consumption Q 1. 52 kg/m~3,. The optimum stope production cost is 32.5 yuan / t, which is 2.64 yuan / t less than that of the original stope production cost, and the average block size is 41.4 cm,. The bulk rate and average block size are in a reasonable range, which provides the basis for mine production.
