In response to the insufficient research on damage weakening evolution law of surrounding rock during roadway (tunnel) excavation and retreat, as well inadequate understanding anchoring mechanism bolts in such masses, a series triaxial loading-unloading uniaxial reloading experiments were conducted sandstone specimens using RMT-150 C mechanics testing system. Microstructural characteristics damaged mass investigated through scanning electron microscope (SEM) analysis, revealing rock. Through...
When cutting roof and pressure relief, the impact of blasting is especially obvious on integrity a large-section soft-rock roadway. The reasonable parameters were studied through using Xiaohezui coal mine -12110 roadway as engineering background. LS-Dyna simulation results show that: Interval beneficial to expansion interhole cracks damage perimeter hole smaller than that adjacent blasting, lower charge uncoupling factor, larger fragmentation zone. mechanical model after retrieval was...
The mining of deep coal resources occurs in a high-stress geological environment as well an engineering rock excavation and unloading. Research on the re-bearing capacity characteristics damage mechanism masses damaged by peak front unloading is critical revealing destabilization rupture law bodies. triaxial pre-peak point was controlled to prepare sandstone specimens, RMT-150C mechanics test loading system AEwin USB-type acoustic emission monitor were used perform uniaxial reloading tests...
Through the analysis of project gob‐side entry retaining in deep gangue filling 2305S‐2# working face Xinjulong coal mine, principle and technology surrounding rock control along mining are discussed. It is found that use to fill goaf can effectively alleviate occurrence violent strata pressure, which basis for realizing goaf. In wall concrete‐filled steel tube columns used as roadside support structure. Anchor bolt + W belt advance support, monomer column hinged beam temporary long anchor...
In view of the frequent occurrence roof accidents in coal roadways supported by bolts, widespread application bolt support technology has been restricted. Through on‐site investigation, numerical analysis, and other research methods, 6 evaluation indicators were determined, according to relevant factors four types roadway stability, a neural network structure for stability prediction was constructed realize quantitative bolt‐supported roadway. The method adding momentum is used improve BP...
