松动爆破在长平矿生产掘进中的应用研究

Research on the Application of the Loose Blasting Method in the Tunneling of the Changping Ore

阐述了松动爆破的机理、理论计算及工程试验情况,介绍了松动爆破防治机采工作面煤与瓦斯突出技术在长平矿的试验研究。实施松动爆破措施后,达到了防突及加快工作面掘进进度的目的。

The principle of the loose blasting method , the theoretical calculation and the situation of the engineering calculation are analyzed in detail. The application of the coal of the prevention and control of the loose blasting mining face and gas outburst technology in the experiment research on the Chang-ping ore are introduced. The experimental data show that, the loose blasting method is good to prevent and control gas outburst and speed up the working face advance.
