The authors consider the construction problems of an economical and environment-friendly steam accumulator locomotive for industrial railway transport. In comparison to diesel locomotives, this locomotive allows to abandon diesel engines and reduce repair and maintenance costs. This locomotive can be used in dusty and contaminated conditions without reducing the resource and in enterprises requiring explosion protection and fire safety.

Two decision trees for contract and reclamation work of the enterprise implemented in the Python high-level programming language have been built. The influence of different indicator sets on the result of building the decision tree is considered. The recommendations for setting target sets for the effective application of an intelligent decision support system are presented.
The article considers the occupational health issue of the workers engaged in coal loading and unloading operations. Such factors as noise, vibration, microclimate, and dust pollution are considered. Preventive measures to control these factors are proposed.
