现代工业发展对煤炭能源的需求量不断加大,煤矿开采事业也由此得到了进一步的发展。我国地域辽阔,不同地区的成矿条件和原因各不相同,在新技术和新工艺的广泛应用下,在复杂地质条件下进行煤矿开采工作越来越多。在复杂地质条件下进行煤矿开采首先要保证的就是采矿人员的人身安全,这其中就离不开掘进支护技术的应用。 The demand for coal energy in the development of modern industry has been constantly increasing, and the cause of coal mining has been further developed. China has a vast territory and different metallogenic conditions and causes in different regions. With the extensive application of new technologies and new processes, more and more coal mines are being exploited under complicated geological conditions. In the complex geological conditions for coal mining is the first to ensure that the safety of miners, of which one can not do without the application of supporting technology.
