摘要
针对赵庄二号井2309初采工作面揭露断层破碎带的实际情况,提出采用注浆加固技术对破碎带围岩进行加固,并对注浆参数及注浆流程进行了设计;为保证2309初采工作面顺利通过断层破碎带,阐述了应采用的回采工艺措施;注浆加固技术和优化回采工艺可保证工作面安全高效通过断层破碎带。
Aiming at the actual situation of fault fracture zone exposed in the 2309 primary mining face of Zhaozhuang No.2 well,the grouting reinforcement technology was proposed to strengthen the surrounding rock of the fracture zone,and the grouting parameters and grouting process were designed;The mining face passed the fault fracture zone smoothly,and the mining process measures to be adopted were explained.The grouting reinforcement technology and the optimized mining process can ensure that the face can pass the fault fracture zone safely and efficiently.
