随着煤炭需求的增加,煤炭开采速度也在不断加快,开采的深度也在不断加大,并已进入到了深部开采的阶段。煤矿深部开采过程中存在地温高、瓦斯的含量大以及地压大等特点,因此在煤矿开采的环节,只按照浅部开采的规律和特征对深部开采中的情况进行分析和处理,远不能满足深度开采的要求,其相对浅部开采的风险更高。在煤矿生产过程中,煤矿矿井进行深部开采时,需合理、科学的应用深部开采理论,并为其深部开采提供安全、经济以及有效的技术依据。
With the increase of coal demand, coal mining speed is also accelerating, mining depth is also increasing, and has entered a deep mining stage. Due to the characteristics of high ground temperature, large gas content and large ground pressure in the process of deep mining, the conditions of deep mining are analyzed and dealt with according to the laws and characteristics of shallow mining only in the part of coal mining, far from satisfying Deep mining requires a higher risk of mining relative shallowness. In the process of coal mine production, deep mining in coal mines requires rational and scientific application of deep mining theory and provides a safe, economical and effective technical basis for its deep mining.
