The paper describes the in-situ test data and mathematical modeling results on ventilation in long (more than 10 m) blind stopes during operation of load–haul–dumpers with combustion engines. The change in the toxic gas concentration versus the running time of the machinery in the stopes is determined, and the appropriate relations are derived.
