The invention relates to the technical field of mine support, and provides an operating condition simulation method and operating condition simulation test bench for an anchor bolt support system. Theoperating condition simulation method for the anchor bolt support system comprises: simulating the surrounding rock of a roadway by a model in order that the shape of the free surface of the model isconsistent with the shape of the surface of the surrounding rock before deformation, wherein the surrounding rock of the roadway is the surrounding rock where one of a roof, a floor and a laneway islocated; mounting an anchor bolt and a bolt surface protecting member on the free surface of the model in comparison with a downhole roadway, and mounting a measuring device corresponding to the boltsurface protecting member; measuring the surface deformation of the surrounding rock of the downhole roadway; applying pressure to the surfaces, other than the free surface, of the model in order thatthe deformation amount of the free surface coincides with the surface deformation amount of the surrounding rock of the roadway; and acquiring the stress and / or deformation of the bolt surface protecting member by the measuring device. The operating condition simulation method for the anchor bolt support system can provide a theoretical basis for the research of an anchor bolt support theory andthe anchor bolt support design under complex stress conditions.
Description
technical field [0001] The invention relates to the technical field of mine support, in particular to a working condition simulation method and a working condition simulation test bench of a bolt support system. Background technique [0002] Bolt support, as a safe and efficient main support form for coal mine roadways, has been widely used in coal mine roadways in my country. Bolt support is to anchor the bolt in the coal and rock body, tighten the nut at the end of the rod to apply prestress to the surrounding rock, and restrain the deformation, separation, swelling and slippage of the surrounding rock of the roadway. The roadway bolt support system consists of the roadway roof and floor, two sides of surrounding rock, bolt force members, and surface protection members that restrain the surrounding rock. Perpendicular to the axis of the roadway, the bolts in the roadway are arranged in rows along the section of the roadway, and each row of bolts is installed with a steel ...
