摘要
根据坚硬顶板的特点与控制理论,针对前人提出的理论及最新的技术与工程实践经验进行分类整理,比较爆破法、注水法以及联合弱化法之间的优劣性及适用范围,得出爆破法虽然应用广但安全性较差,注水法虽然安全性好但对岩层吸水性要求较高,联合弱化法综合各顶板弱化方法优点,但是应用还不成熟仍处于探索阶段.总结坚硬顶板弱化技术仍需改进的地方及为以后的发展方向提供建议,并为坚硬顶板的弱化技术的研究以及在工业中的应用提供借鉴.
According to the characteristic of hard roof and control theory, and in view of the predecessors＇ theory and the latest technology and engineering practical experience for sorting, this paper compares the advantages and the disadvantages and applicable scopes between blasting method, water injection method and joint weakening method. It concludes that the blasting method is widely used, but its security is bad; the security of the water injection method is good, but the requirements for rocks water absorption are higher; and the joint weakening injection method integrates the weakening advantages, but its application is not mature and is still at the exploratory stage. This paper summarizes that the hard roof weakening technology still needs to be improved, and advises for future development direction. It also provides references for the research of hard roof weakening of technology and application in the industry.
