Reinforcement and Outburst Prevention Technology of Reserved Coal in Advance Excavation of Soft High-outburst Coal Seam

Drilling-induced and outburst prevention technology and equipment of soft coal seam high-outburst areas is a new technology. Coal within advance distance is taken as the research object, and mechanical principles are used to analyze it. From the mechanical balance point, temporary reinforcement program is proposed, which is a fundamental solution to induced outburst issue in the drilling process with high Innovation. Especially the one-time anchoring agent fixator is smartly designed to solve the contradiction between anchoring and tunnelling. The technology theory is mature, and it will play a significant role in excavation and outburst prevention of soft coal seam high-outburst areas after improving the construction process.
