摘要
Abstract
A new type of underground negative pressure drainage sealing hole process is analyzed in detail and the performance of grouting material is tested, and the length of sealing hole is determined by FLAC2D numerical simulation. The feasibility of the technique is verified by field test in N2202 working face. It is a very good solution for the high gas coal mine to realize and solve the problems of the coal mine gas.关键词
