摘要
针对赵庄二号井2314回采工作面过富水陷落柱工程实际,为保证生产安全且获得的技术经济效益最大化,运用注浆加固的方法来防控工作面过陷落柱可能引起的突水灾害。提出合理的钻孔位置、钻孔设计、施工顺序及加固措施,并进行了效果检验。实现消除突水及滞后导水威胁,有效降低围岩变形,保证了回采工作正常有序进行,对赵庄二号井工作面过富水陷落柱具有积极的指导及借鉴价值。
Aiming at the actual project of over-water-falling columns in the 2314 working face of Zhaozhuang No. 2 well, in order to ensure the safety of production and maximize the technical and economic benefits, grouting and strengthening methods are used to prevent and control the over-falling columns in the working face Water inrush disaster. Reasonable drilling positions, drilling design, construction sequence, and reinforcement measures were put forward, and the effects were checked. It can eliminate the threat of water inrush and lagging water conduction, effectively reduce the deformation of surrounding rocks, and ensure the normal and orderly recovery of mining.
