Bulk resin injection system

A bolting device, comprising:

• a frame including a boom;
• a bolting attachment including a wand coupled to the boom, the wand configured to extend or retract with respect to an initial position;
• and
• a pump system in communication with the wand and configured to pump resin and catalyst thereto,
• wherein the pumping of resin and the pumping of catalyst by the pump system are performed independently.

A resin injection system, comprising:

• a pressurized resin tank configured to hold a supply of resin, the pressurized resin tank in communication with a first continuous pump coupled to a first hydraulic cylinder;
• a pressurized catalyst tank configured to hold a supply of catalyst, the pressurized catalyst tank in communication with a second continuous pump coupled to a second hydraulic cylinder;
• a hydraulic source configured to supply a flow to the first hydraulic cylinder and the second hydraulic cylinder;
• a flow divider positioned between the hydraulic source and the first and second hydraulic cylinders, the flow divider configured to distribute the flow generated by the hydraulic source between the first and second hydraulic cylinders;
• a wand in communication with the pressurized resin tank and the pressurized catalyst tank, the wand configured to inject at least a portion of the supply of resin and at least a portion of the supply of catalyst into a hole;
• a control panel configured to enable an operator to input one or more parameters associated with a particular application or operation;
• and
• a processor configured to receive the information input by the operator,
• wherein the first and second pumps operate independently with respect to one another,
• wherein the processor is configured to determine a desired ratio between resin and catalyst, a desired rate of retraction of the wand during an injection operation, or both, and
• wherein the ratio between resin injected via the wand and catalyst injected via the wand can be adjusted by altering a configuration of the flow divider.
