ARMORED DETECTOR

摘要

An armored detector assembly (30), a mining system (10), and methods of using it are described. The armored detector assembly (30) consists of a main assembly (32) and a hatch assembly (74). The armored detector assembly (30) houses sensitive monitoring equipment (100) used in mining operations. One embodiment allows for openings (50) in the main assembly so that gamma radiation can enter the main assembly (32) and be measured by gamma radiation monitoring equipment (100) used in continuous mining operations. A portion of the gamma radiation monitoring equipment is enclosed within an integral explosion proof enclosure (120). This embodiment contains a fluid channel (58) and a plurality of spray orifices (60) to reduce the risk of ignition of dust or gas and other orifices for removal of mining debris from the openings in the assembly.
