In underground coal mines there are several risks that threaten the safety of your operation, your facilities and your personnel. One of the most critical hazards is that associated with possible explosions inside the mine that can generate great economic and human losses. Among the factors that must be taken into account, even more than the possible methane pockets found during the excavation, is the high concentration of coal dust. Carbon dust, being in high concentrations, is extremely flammable and an explosion caused by this generates a chain reaction as it spreads rapidly throughout the mine. Because of this the mines must create an inert environment by adding limestone or rock dust to the walls of the mine and to the environment trying to always maintain a low concentration of coal dust. The CDEM 1000 was developed in conjunction with the NIOSH and MSHA to provide a portable tool that would immediately let the mines know if the environment inside is inert immediately without waiting for laboratory results, letting know if the conditions of work are appropriate or not. This equipment is also used to optimize the use of inert material in such a way that it does not exceed its expense and maintain the balance of Rock Dust and Coal Dust at the lowest possible cost. The CDEM 1000 was developed in conjunction with the NIOSH and MSHA to provide a portable tool that would immediately let the mines know if the environment inside is inert immediately without waiting for laboratory results, letting know if the conditions of work are appropriate or not. This equipment is also used to optimize the use of inert material in such a way that it does not exceed its expense and maintain the balance of Rock Dust and Coal Dust at the lowest possible cost. The CDEM 1000 was developed in conjunction with the NIOSH and MSHA to provide a portable tool that would immediately let the mines know if the environment inside is inert immediately without waiting for laboratory results, letting know if the conditions of work are appropriate or not. This equipment is also used to optimize the use of inert material in such a way that it does not exceed its expense and maintain the balance of Rock Dust and Coal Dust at the lowest possible cost.
