摘要
叙述了伯方煤矿三盘区3308综放工作面工程概况,从沿空留巷充填系统设计和沿空留巷技术应用两方面对井下沿空留巷开采技术进行了论述,并对其具体应用效果进行分析,证明了沿空留巷在提升井下回采效率上的有效性,希望能为其他矿井沿空留巷回采的开展提供一定的借鉴。
This paper described project overview of 3308 fully mechanized caving face at No.3 panel of Baifang Coal Mine, discussed the technology used in retaining roadways along goaf from two aspects： design of filling system used in retaining roadways along goaf and application of technology used in retaining roadways along goaf, analyzed its application effect and proved that the effectiveness of the retaining roadways along goaf has effectiveness in improving mining efficiency, which hoped that it can provide some reference for the development of mining in retaining roadways along goaf in other mines.
