湖南省煤炭储量较大,大多数煤矿地质构造复杂,煤炭贮存极不稳定,开采条件差,是典型的水、火、瓦斯、煤尘、顶板灾害俱全的重灾区。而湖南省资兴唐洞煤炭有限责任公司唐洞煤矿就是一个比较典型的煤矿,其最厚的煤层不过3m,而最薄的煤层不足0.45m,开采条件差,安全生产任务繁重。近 Hunan Province has a large coal reserve. Most coal mines have complex geological structures, unstable coal storage conditions and poor mining conditions. They are typical hardest hit areas in water, fire, gas, coal dust and roof disaster. However, Tangdong Coal Mine of Zixing Tangdong Coal Company of Hunan Province is a typical coal mine whose thickest coal seam is only 3m, while the thinnest coal seam is less than 0.45m. Its mining conditions are poor and its safety production tasks are heavy. near
