沙曲矿为双突高瓦斯矿井,瓦斯严重制约着矿井正常生产,为此,沙曲矿在4.5m厚煤层中全国首次实验研究应用沿空留巷“Y”型通风,实现煤与瓦斯共采。此项技术的实验应用,为我国类似条件下的高瓦斯、中厚煤层矿井解决瓦斯治理难题,实现煤与瓦斯共采提供了实践和技术的双重指导,对改善我国煤矿高瓦斯双突矿井安全生产具有重大意义。
Shaqu mine is a double-gassy high-gas mine, gas seriously restricts the normal production of mines, therefore, Shaqu mine in 4.5m thick coal seam in the country’s first experimental study of the use of gob-side entry “Y ” type of ventilation to achieve coal and Methane mining. The experimental application of this technology provides a dual guide for practice and technology for solving the gas treatment problems in the high-gas and medium-thickness coal mines under similar conditions in our country, and realizing double co-mining of coal and gas. Production is of great significance.
