在回采巷道中,锚杆支护已取代大量的架棚支护,它省工省力、操作方便、锚固力大、安全可靠、经济效益明显,已被广大煤矿职工及工程技术人员接受。锚杆支护所用的树脂锚固剂,是根据锚杆支护的作用原理和使用技术要求而研制生产的高分子粘结锚固材料。对锚杆支护除参数优化设计、顶板岩性分析及锚杆孔要求技术条件外,本文着重研究树脂锚杆的安装工艺及其对顶板的控制,一是锚固力(抗拔力),二是托锚力
In the mining roadway, bolt support has replaced a large number of shelving support, it saves labor and labor, easy operation, anchoring power, safe and reliable, obvious economic benefits, has been the majority of coal mine workers and engineering and technical personnel to accept. Anchor resin used in bolt anchoring agent is based on the principle of bolt support and the use of technical requirements and development and production of polymer adhesive anchoring material. In addition to the parameter optimization of rock bolt support design, roof rock analysis and bolt hole requirements of technical conditions, this paper focuses on resin bolt installation process and its control of the roof, the first one is the anchoring force (anti-pull force), the second Is the anchor force
