摘要
煤炭是我国的主要能源,是我国经济发展的基础产业。在煤矿开采的过程当中,为了保证煤矿开采的安全以及煤炭资源开发的质量,需要对煤矿掘进巷道技术和巷道顶板管理等一系列的技术进行研究,顶板事故在煤矿开采的过程中占有很大的比重,甚至会在掘进过程中造成冒顶事故。因此,只有在煤矿掘进过程中全面加强对顶板的控制和管理,才能保证安全掘进。本文结合实际薄基岩下巷道掘进对顶板管理的案例,主要分析薄基岩下巷道掘进顶板管控技术的应用。
Coal is the main energy source in our country and the basic industry of economic development in China.In the process of coal mining,in order to ensure the safety of coal mining and the quality of coal resources development,it is necessary to study a series of technologies such as coal mine excavation roadway technology and roadway roof management,the roof accident in the process of coal mining accounted for a large proportion,and even in the process of mining caused a roof accident.Therefore,only in the process of coal mining to strengthen the control and management of the roof,it can ensure the safe excavation.Based on the case of the management of the roof,this paper analyzes the application of the control technology of the tunnel under thin bedrock.
