Abstract: A continuous mining and delayed filling mining method for a deep ore body masonry structure is provided, comprising: dividing an ore body into ore blocks along a trend, internally dividing each ore block into stopes with square masonry structures, and reserving a rib pillar between the ore blocks; arranging an ore block conveyor belt gallery and a stope conveyor belt gallery at the lower parts of the ore blocks, arranging ore block crossheading and stope crossheading at the upper parts of the ore blocks, mining the stopes in the sequence from the foot wall to the hanging wall. In accordance with the present disclosure, adverse effects caused by deep high geo-stress and high geo-temperature on mining operation can be effectively overcome. The method has the advantages of low carbon and environmental protection, safety of recovery operation, high mechanization of stope operation, low labor intensity of manual operation and the like.

Abstract: A rock true triaxial dynamic compression-shear test equipment, and method under deep complex structure conditions, includes a counterforce framework, a pressure chamber, a base platform and four actuators. A pressure chamber transfer track is arranged on the base platform, and a pressure chamber transfer slipway is arranged on the tracks. The pressure chamber is a split structure. A pressure chamber base is located on the pressure chamber transfer slipway, and a pressure chamber barrel is provided with a pressure chamber barrel lift type bearing table and a pressure chamber barrel hoisting mechanism. The pressure chamber is provided with pressure chamber barrel and base packaging fixtures.
