【摘要】 通过理论和实践研究,提出了三面采空综放采场"C"型覆岩空间结构运动的矿压显现规律和相关矿压控制技术.此类采场矿压控制的理论基础是采场"C"型覆岩空间结构运动及其与采动应力场的关系;其工程问题是工作面巷道和切眼围岩矿压加剧造成的灾害形式及其控制技术和因坚硬岩层断裂引起的冲击地压的可能性预测和防治技术.通过兖州煤业股份有限公司南屯煤矿的工程实例,系统介绍了矿压灾害监测技术和控制方法.结果表明,文中提出的对岩层结构的认识和采取的监测控制技术是正确的,可以在条件相似的矿区推广应用.更多还原

【Abstract】 According to the theoretical and practice research,the overlying C-shaped strata structure and mining pressure control techniques for sub-level long wall face surrounded by three sides mined areas were presented.The key theoretical foundation is how to consider the relationship between C-shaped strata spatial structure and mining pressure field.The key techniques are as follows: the disaster forms and control techniques owing to pressure aggravate of tunnel;the possible forecast and the control techniques of rock burst owing to hard rock stratum break.The thesis introduces disaster monitoring and control techniques in Yankuang Group Nantun Coal Mine,the results make clear that these techniques can be used in coal mines with similar conditions.更多还原
