Abstract: A safety enclosure for use with underground mining machinery for protecting the operator of the machinery from overhead and lateral falls and the like. The safety enclosure comprises a cage-like structure of generally rectangular cross section for receiving and surrounding the operator while operating the machine. A pair of longitudinal male slide members are vertically secured to the cage-like structure along one side thereof, the slide members being slidably mateable with a pair of cooperating female channel members vertically secured along one side of the mining machine. Shear pins are provided for adjustably maintaining, under normal operating conditions, the cage-like male slide members assembly disposed above the mine floor by a preselected distance and for releasing the assembly for sliding displacement to the floor of the mine in response to an overhead fall causing a predetermined force on the top of the enclosure.
