Description

Technical field [0001] The invention relates to mine support technology, in particular to a movable anchoring drill carriage during the final mining of a coal mining face. Background technique [0002] During the final mining of the coal mining face, the support method for the face removal is supported by wooden beams and single pillars. The geological conditions of our mine are complex, and installation and removal are frequent. The traditional support method has high labor intensity, low safety factor and poor economy. And other drawbacks. [0003] Innovative support methods are now innovated. The roof support adopts the composite support method of anchoring rods, anchor cables, laying steel ladders, and binding steel ropes under the flexible net laid on the roof, which greatly improves the support strength and safety. Due to the innovation of the working face support method, the final mining conditions require a lot of drilling operations. The traditional drilling rig has heavy...

Problems solved by technology

[0005] In order to solve the following main technical problems: first, the anchor drilling rig should be able to tow and walk by itself, so as to solve the problems of low efficiency and slow moving speed of the existing pneumatic rod drilling rig; The mechanized construction of anchor (cable) holes at different heights and angles in the mining face can realize the simultaneous operation of roof and side, and the drilling construction of the entire section can be completed in one positioning
