摘要
以沙曲矿14203工作面为例,通过对综掘工作面两种防突方案的比较,确定深层预抽为合理的掘进方案,指出该方案对实现快速掘进具有重要的现实意义。
Taking 14203 working face in Shaqu Mine as an example, this paper compares two outburst prevention schemes of fully mechanized workface, determines that deep pre-drainage is a rational tunneling scheme, and points out that this scheme has practical significance for implementing the quick tunneling.
