    To establish support quality indicators, it is necessary to combine many specific conditions and requirements, including environmental conditions, technical preparation requirements, material quality requirements, operating conditions requirements, technical quality requirements. The process objectives are also related to the relevant processes. For example, the bolt pull force is also the target of the entire support process. Although its goal is relatively clear, if the surrounding rock lithology is neglected, its quality target will be lost. In the case, turning a single drug roll into a double drug roll is also the way to achieve this process goal.
    There are many processes in the roadway support process, in which the anchoring of the anchor can be listed as an important process. The so-called anchoring process can be understood as the process of restraining the surrounding rock by the anchor. In this way, the quality index of the anchoring process can be considered from the main control item of the quality inspection. The main point is that the pullout force index of the anchor and the anchor tray are close to the surrounding rock, which is the key to make the surrounding rock play a role, and also the uranium rod. The key to construction quality.
How to carry out quality control of roadway support technology? How to establish support technology goals?
    Quality control of the roadway support process is carried out throughout its planning, execution, inspection and feedback processes. Roadway anchor spray support is generally a relatively mature process, so the control content is relatively simple, but also neglected because of maturity . The content of the case reflects this negligence, such as the planned double-drug material arrangement, the implementation of the dual-pill operation requirements, and the actual operation is not standardized. It is found that the support effect is not satisfactory, and the feedback processing is not required at the time to wait for the on-site inspection. The project department issued an order to request corrections and other issues, indicating the defects in planning, execution, and inspection feedback in the quality of the control support process.
