深孔预裂爆破技术在工作面过陷落柱的应用
|
摘要
基于工作面过陷落柱的难题,以2103工作面所遇XLZ6陷落柱为研究对象,通过对比分析提出了采用深孔预裂爆破技术过陷落柱。2103工作面过XLZ6陷落柱实践表明,通过深孔预裂爆破技术的实施,可有效增加陷落柱岩体裂隙,提高其岩体碎裂度,为安全高效过陷落柱奠定了基础。
Based on the problem of crossing collapse column in working face, taking XLZ6 collapse column encountered in 2103 working face as the research object, the deep hole pre-splitting blasting technology is put forward through comparative analysis. The practice of passing XLZ6 collapse column in 2103 working face shows that the implementation of deep-hole pre-splitting blasting technology can effectively increase the cracks of collapse column rock mass and its rock fragmentation, laying a foundation for safe and efficient passing collapse column.
