Distributed anchoring and grouting support device for deep mine fault fracture zone

Abstract

The invention belongs to the technical field of mining equipment, and particularly relates to a distributed anchoring and grouting support device for a deep mine fault fracture zone. The distributed anchoring and grouting support device comprises a working platform, wherein a first motor installed on the top face of the working platform is in driving connection with a base through a driving gear, an idle wheel and a driven gear; an outer sleeve and a second hydraulic rod are fixedly installed on the top face of the base; the top face of an inner sliding rod connected to the top end of the second hydraulic rod is rotationally connected with a fixing base; the front side face of the inner sliding rod is rotationally connected with the fixing base through the second hydraulic rod; a translation arm is installed on the inner side of the fixing base in a sliding mode; a translation mechanism is installed on the top face of the fixing base; an electric pick and a grouting spray head are installed at the front end of the translation arm through a connecting sleeve; and the grouting spray head is connected with a stirring tank through a hose and a cement pump. Cement can be used immediately after being adjusted through the stirring tank and a stirring anchor, then the positions of the movable electric pick and the grouting spray head are adjusted, so that the operation of distributed anchoring and grouting support in a roadway and a shaft is completed, and the support level and the support efficiency are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of mining equipment, and in particular relates to a distributed anchoring and grouting support device for fault fracture zones in deep mines. Background technique [0002] The deep high-stress soft rock has the characteristics of large deformation and long rheology. The deformation and failure of the roadway is the result of the continuous development of the plastic zone and fracture zone of the surrounding rock of the roadway to the deep part of the surrounding rock. The deformation and failure of the high-stress soft rock roadway are not instantaneous, but are the result of a dynamic deformation process after the surrounding rock changes from a three-dimensional stress state to a two-dimensional stress state after excavation. The continuous development of the plastic zone and the crushing zone is the prerequisite for the mudification of the surrounding rock caused by the highly confined water. Due to the ...
