摘要
采空区瓦斯运移规律的相似性实验通过采用相似理论试验模型模拟不同通风方式采空区瓦斯浓度场的分布和瓦斯运移规律,为工作面通风方式的选择方面提供一定的理论支持,同时可以帮助矿井有效地解决工作面上隅角瓦斯等问题。
The similarity experiment in the goaf is carried out by using the similarity theo1y test model to simulate the distribution of the gas concentration field and the gas migration law in the goal under different ventilation modes, and provide some theoretical support for choice of ventilation mode in working face. At the same time can help the mine effectively solve the top corner gas of the working face.
