摘要(Abstract):
通过小规模爆破试验,用线性回归方法对块煤进行筛分分析,指出影响炮采工作面块煤率的因素是炸药性能、装药结构、爆破参数、起爆顺序、时间间隔等。
In this paper,a small-scale explosion test is introducedA screening analysis on block coal was carried out with linear regressionIt is pointed out that factors influencing the block coal rate are explosive property,charging structure blasting parameters,initiating order,time interval,and so on
