巷道支架后部加固区灌浆,是在复杂的矿山地质条件下保持巷道稳定的一种有效措施。加固区灌浆的主要参数是灌浆工作滞后于掘进工作的时间,以及要求的灌浆固结块的单轴抗压强度。这个抗压强度按加固区灌 Grouting at the rear reinforcement zone of roadway brackets is an effective measure to keep the roadway stable under complicated mine geological conditions. The main parameters of grouting in the reinforcement zone are the lag time of the grouting work and the uniaxial compressive strength of the required grouting consolidation. This compressive strength by reinforcement zone irrigation
