煤体松动爆破在综采工作面的应用

Application of Coal Body Loose Blasting in Fully Mechanized Working Face

综采工作面初采时若遇到煤层较硬的情况下,采煤机割煤将很困难,将煤体松动爆破技术应用到综采工作面初采,起到了较好的效果,为工作面初采正规循环作业提供了技术保证。

In the fully mechanized working face when meet a hard if coal seam,under the situation of coal winning machine would be very difficult to cut coal,in this paper,the coal body loose blasting technology is applied to in the fully mechanized working face,played a good result for mining face in the normal circulation work provide the technical guarantee.
