Today?s autonomous and heterogeneous information systems have an increasing necessity of exchanging data. As widely known, middleware systems have been successfully adopted as infrastructure for communicating those systems. In addition to provide basic communication services, however, the necessity of bringing together business services to the middleware is apparent in many domain-specific applications. In this context, we propose a MOM-based solution for remote monitoring of equipment for maintenance of mines. This solution is actually under operation and has been developed with the sponsorship of Modular Mining System?, world's leader in mine management technology, and incorporates particular requirements of the communication between mining companies and equipment manufacturers, whilst it takes advantages of the communication model of MOMs.
