斜井小坑在掘进中出渣,过去我们一直是用人背,不仅劳动强度大,且运输效率极低,尤在掘进速度快,每班达数米以上时,运碴到坑外,就成为一个突出的问题,甚至直接影响到掘进速度的提高。为此,五星分队马脖子地段26号坑,在坑长40—50公尺,坡度20°的条件下,试用了斜井木绞车,如图,其 Slope pit excavation in the slag, in the past we have been employing the back, not only labor-intensive, and the transport efficiency is very low, especially in the tunneling speed, more than a few meters per class, the ballast to the pit, it becomes A prominent problem, and even directly affect the improvement of driving speed. To this end, five-star unit Ma neck section pit 26, 40-50 meters in pit length, slope 20 ° under the conditions of trial inclined shaft winch, as shown
