PRODUCTION OF MULTI-COMPONENT PLASTICS MATERIAL FOR USE IN UNDERGROUND MINING

摘要

Foam generating equipment for use in mines includes supply vessels for the resin and foaming agent located in a central stores location. An air compressor is also located there. A pair of pumps in a protective casing transportable by an operator have inputs receiving the resin and foaming agent and outputs connected to a foaming gun. The pumps have a common power supply connection coupled to the air compressor. The pumps in the casing are carried by the operator and deposited at a temporary location in proximity to the site where the foam is to be emplaced. The spray gun is then operated to emplace the foam at the site.
