The NOHSM consisted of 491 mine surveys. The mines were selected so as to be statistically representative of the entire U.S. mining industry. At each mine, NIOSH employees obtained data regarding occupational hygiene programs, potential exposure to chemical and physical agents, and bulk dust samples. The NOHSM survey data have been automated in the NOHSM Query System. This system allows queries to be processed against the data collected during the NOHSM survey. The NOHSM Query System was developed to be user friendly so that end-users can process their own queries against the NOHSM data. This was accomplished by making the system key driven with on-line help, and simplifying the query formulation process by minimizing the selections. There are two steps in formulating a query. Step one is deciding which data to retrieve or how to... |
