坪湖煤矿B_4煤层瓦斯赋存地质特征分析

Geological Characteristic Analysis of Gas Occurrence on B_4 Coal Bed in Pinghu Colliery

随着矿井开采深度的增加,煤层瓦斯压力增大、含量增高、突出危险性增大。因此,研究、认识和掌握瓦斯赋存规律,有针对性地制定瓦斯治理和施工措施,消除煤层瓦斯瓦斯突出危险性,确保矿井安全高效和可持续发展具有深远意义。

Mining depth increase leads to seam gas pressure and concentration increase, outburst hazards increase as well. The authors propose it is necessary to study, understand and master gas occurrence regularity, formulate gas control and construction measures to eliminate seam gas outburst hazards, which has far--reaching significance for efficient and sustainable development of mine safety.
