Abstract: A pumpable resin system for installation of mine bolts includes a resin injection cylinder comprising a resin chamber and a resin hydraulic cylinder, a catalyst injection cylinder including a catalyst chamber and a catalyst hydraulic cylinder, with the resin hydraulic cylinder synchronized with the catalyst hydraulic cylinder, a hydraulic pump in fluid communication with the resin hydraulic cylinder and the catalyst hydraulic cylinder, a hydraulic reservoir in fluid communication with the hydraulic pump, and a delivery line in fluid communication with the resin injection cylinder and the catalyst injection cylinder. The delivery line is configured to deliver resin and catalyst from the resin injection cylinder and catalyst injection cylinder into a borehole.

Abstract: A mine bolt bending system includes a frame comprising a plurality of bolt receiving portions each configured to receive and hold a mine roof bolt, a bolt contact member secured to the frame, with the bolt contact member rotatable relative to the frame between a first position and second position, and an actuator secured to the frame, with the actuator configured to move the bolt contact member between the first and second positions. The bolt contact member is configured to bend a mine bolt when rotating from the first position to the second position.
