提高炮采工作面块煤率的爆破技术

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。

STUDY ON BLASTING TECHNOLOGY OF INCREASING PRODUCTION RATE OF BLOCK COAL IN STOPES

In this paper,a small-scale explosion test is introducedA screening analysis on block coal was carried out with linear regressionIt is pointed out that factors influencing the block coal rate are explosive property,charging structure blasting parameters,initiating order,time interval,and so on
