“Y”型通风解决矿井隅角瓦斯积聚的应用技术

Application technology of preventing mine corner gas accumulation with Y-type ventilation method

新元公司是典型的高瓦斯突出矿井,为解决隅角瓦斯积聚问题,利用沿空留巷技术实现"Y"型通风。通过与"U+L"型通风方式相比较,得出这种"Y"型通风方式可以有效解决隅角瓦斯积聚等问题。

Xinyuan Coal Mine is a typical high-gas and outburst mine. In order to solve the problem of corner gas accumulation,the Y-type ventilation with gob-side entry retaining technology was adopted. Compared with the U + L type ventilation method,the Y-type ventilation method can solve the problem of corner gas accumulation effectively.
