摘要
济宁二号煤矿11302冲击地压孤岛综放工作面属兖矿集团A级隐患面。针对工作面矿压显现强烈,且过中间巷,回采工序异常复杂,通过对工作面设计优化,回采技术创新等一系列措施,解决了工作面回采过程突显的难题,以综合预防与治理为原则,确保了工作面的安全回采。
11302 fully mechanized top coal caving face at isolated un-mined area with rockburst of Jining No.2 Coal Mine belongs to A level risky faces of Yancon Group.Because of the intense pressure behavior and the situation of passing middle entry,the recovery process is extraordinary complex.Through series measures such as optimization of face design and innovation on recovery technique,problems featured during the recovery process are solved.Taking overall prediction and prevention as principle ensures a safety recovery.
