Abstract
A pumpable resin system for installation of mine roof bolts includes a resin reservoir configured to receive resin, a catalyst reservoir configured to receive catalyst, a resin pump arrangement in fluid communication with the resin reservoir, a catalyst pump arrangement in fluid communication with the catalyst reservoir, a delivery line in fluid communication with at least one of the resin pump arrangement and the catalyst pump arrangement, and a bolter arm configured to drill boreholes and install mine roof bolts. The delivery line is configured to deliver resin and catalyst from the resin reservoir and the catalyst reservoir to a borehole via the bolter arm.
