specific Embodiment

[0038] The hole slotting machine consists of four parts: multi-head drilling device, drilling rig platform that can be moved horizontally, drilling anti-deviation device, and overall shifting device of the slotting machine.

[0039] 1. Multi-head drilling device:

[0040] Such as figure 1 As shown, the drilling device is composed of more than two (generally 3 to 5) drill pipes and drill bits, and the drill pipe driving parts are staggered to make the structure of the drilling rig more compact. More than two drill pipe driving parts are fixed on the same platform. During the drilling process of more than two drill bits, they advance and retreat at the same time. Each drilling can drill more than two parallel boreholes on the roadway wall, generally 3 to 5.

[0041] 2. Drilling rig platform with multi-head drilling device that can move horizontally:

[0042] Such as figure 2 As shown, the drilling rig platform includes positioning jacks, platform chassis, platform upper pla...

Abstract

The invention discloses a grooving machine with relief holes. The grooving machine comprises a drilling machine platform comprising a platform chassis. The platform chassis is provided with a vertical guide rail provided with a horizontal guide rail. The horizontal guide rail is provided with a platform hanging wall provided with a multi-head drilling device. The multi-head drilling device comprises a plurality of drilling rods. Each drilling rod is provided with a drive part, a clamping guide device and a drill bit. The grooving machine further comprises a drilling deviation-preventing device, a traveling wheel, a locating jack and the like. The grooving machine can carry out efficient grooving and pressure releasing on a roadway large in buried depth, effectively transfer pressure on a surrounding rock of the roadway to the deep portion of the surrounding rock, improve the self-stabilizing ability of the surrounding rock, lower the supporting counter-force needed by stabilizing of the roadway, and lower the supporting cost.

Description

technical field [0001] The invention relates to equipment for maintaining the surrounding rock of a coal mine roadway, in particular to a hole row slotting machine. Background technique [0002] With the increase of coal mining depth, the original in-situ stress of roadway surrounding rock increases. After the excavation of the roadway, the stress of the surrounding rock of the roadway is redistributed, and the deformation of the surrounding rock of the roadway increases greatly. Roadways under medium-hard and above-medium-hard surrounding rock conditions also exhibit large deformation characteristics of soft rock roadways. Grooving pressure relief is an engineering technology that can effectively release the pressure of the roadway surrounding rock, and is a roadway stability control technology that transfers the pressure of the roadway surrounding rock to the deep part of the roadway surrounding rock. [0003] At present, there is no special slotting equipment or machine...
