摘要
综采工作面超前巷道的支护问题是工作面支护体系的薄弱环节和难点。对超前支护型式的发展进行了阐述,从超前压力分布规律研究、支护参数确定方法和架型3方面分析了超前支护技术和理论的现状,并指出大型和复杂矿井超前支护技术的发展趋势。
Supporting of advance roadway is the weakness and diffi culty in supporting system on the fullymechanized face. In the paper, the development of advance supporting form was discussed, and the status of advance supporting technology and theory were analyzed from such aspects as distribution of advance pressure, determination method of supporting parameters and supporting type. In addition, it indicated the development trend of advance supporting technology in large and complex mines.
