摘　　要：随着开采条件日趋复杂 ,单纯用通风方法解决瓦斯问题已不再合理。文中结合实际探索了在卸压区内用钻孔抽放与采空区瓦斯抽放的具体方法 ,并与传统方法进行了对比 ,效果较好。With the mining conditions is more complexity, simply exhausting way has not been reasonable. This paper studies the detailed ways of exhausting gas form the depress area and goaf by drilling hole combined with practice and compares the ways with traditional ones. The result is better.
