Mesh Locator Magnet SecurityNEWS! The ABM Magnetic Mesh Locater invention described here has received an OH&S award for innovation in mines safety - full details (pdf) From International Longwall news article: Mandalong mesh magic, by Angie Bahr, Monday, 15 September 2008: "As a result of the ABM Magnetic Mesh Locater there has not been an incident involving roof mesh falling and not being retained in position," Mcilveen said. "Mesh is now overlapping more accurately, providing a more stable environment. This allows easier bolting between the meshes and has assisted in increasing productivity and metres." Hunter Valley Mining & Mandalong was commended for its invention at the NSW Minerals Council OHS Innovations Awards in May. 
A safety issue identified at Centennial Coal lead to the design and development of the MESH LOCATOR AND RETAINER MAGNET. Mr. Byron Mcilveen, Development Mechanical Engineer, of Centennial Coal contacted International Magnetic Solutions asking if we could design a magnetic system strong enough to keep the mesh grate in place on the ABM 25 Miner. It all came about from a person hurting himself as the old mesh locator did not retain the mesh and it fell over the front of the miner. 
The purpose of the magnet is to retain and align the mesh making it easier, faster and safer to operate without limiting the workings of the ABM 25 Miner. The MESH LOCATOR AND RETAINER MAGNET is designed to fit the miner and support the cantilever weight of the mesh as it sits in place on the miner in readiness to be bolted to the mine roof. The MESH LOCATOR AND RETAINER MAGNET received extensive trials at Centennial and as a result of these trials the MESH LOCATOR AND RETAINER MAGNET was fitted to a further 4 miners. 
The MESH LOCATOR AND RETAINER MAGNET is specially designed to apply a substantial holding for to the mesh even though the mesh is made from relatively thin and sparsely positioned iron rods. The magnets incorporated in the system are the latest technology highest energy magnets available and in which International Magnetic Solutions has been specializing in since their creation. MESH LOCATOR AND RETAINER MAGNET is totally encased in a mining grade yellow urethane and is structurally reinforced with a substantial steel member. 
The MESH LOCATOR AND RETAINER MAGNET is easily secured in place using 5 M16 shoulder Allen head bolts. The head of the bolts is recessed within the urethane coating providing a flat catch free surface totally eliminating any obstruction to mesh movement. The MESH LOCATOR AND RETAINER MAGNET overall dimensions are 550 x 75 x 30 mm. 
Benefit over other systems.
Installation and Fitting
MESH LOCATOR AND RETAINER MAGNET is supplied in 2 formats.
Fitting is easy.It is done using only 4 M20 bolts which fit into existing ABM 25 Miner threaded holes. It’s done in only one Maintenance shift. There’s nothing more to add! No change to Current Operating Procedure. Steep Grades it’s SAFE.No hassles. The mesh will stay in place without the Danger or need for hooks, ropes or occasional hand.
