MINING AND REQUIREMENTS FOR COAL

Love our channel? This 1930s German silent educational film shows miners descending into the depths of a large coal mine, and then their routine underground. Raw coal is placed into a long conveyor belt and an electric mine train, and then eventually shipped by railroad to the city. The film opens with coal miners deep within a coal mine hacking at the walls of the mine (:29). The workers use axes to pull up boards to erect a conveyor belt for movement of materials (1:26). The completed belt is seen at work moving small pieces of coal through the mine (3:55). Wooden roof joists are hammered into proper position for stability (4:41). A safety fence is set into place (5:31). Machinery grinds the coal face into a powder, shooting it out of a chute into a large pile (6:19). A drill is used to pull softer materials from the mine walls (7:11). Large slabs and chunks of materials are sent down the belt (7:54). A workers sifts through materials by hand (8:12). Sediments are transported in ore cars that are pulled by an electric locomotive (8:31). Motor wheels spin as an elevator moves supplies (11:31).Small ore cars moved by elevator are then re-positioned and tipped over and emptied by a machine (12:12). Larger materials are sorted (12:56) and moved down the line. Workers hand sort some of the coal (13:08). The materials are dumped into a large ore car that is pulled by a steam locomotive (13:21). The film concludes with images of the materials leaving the mine by train (15:05).
