掘进小断面水平探矿巷道时,装岩的主要手段一般是使用铲斗装岩机(当断面大于4米~2时)和手工。由于地质工作的条件特殊,装岩机的时间利用系数仅为12～15%。在巷道断面小于4～5米~2时,用小型的铲斗装岩机效率很低。1959年初,苏联中亚的很多矿山,在掘进各种断面的巷道中,作了大量的电耙装运岩石的生产试验。试验表明,尽管由于缺少空车,设备利用得很不合理,但电耙装运岩石的生产率仍比手工高1～2倍,劳动消耗比手工的少1/2～2/3。据一次测时标定结果表明,电耙装岩的主要工作时间仅
When digging a small section of the level of prospecting roadway, the main means of rock loading is generally used shovel rock loader (when the cross section is greater than 4 m ~ 2) and hand. Due to the special conditions of geological work, rock loading machine time utilization coefficient of only 12 to 15%. When the roadway section is less than 4 ~ 5m ~ 2, the efficiency of using a small bucket rock loader is very low. At the beginning of 1959, many mines in Central Asia of the Soviet Union made a large number of production trials of electric rake shipping rock in the tunneling of various sections. Experiments show that despite the unreasonable use of equipment due to the lack of empty cars, the rock productivity of electric rakers is still 1 to 2 times higher than that of hand-made ones and the labor consumption is 1/2 to 2/3 less than that of hand-made ones. According to a time calibration results show that the main working hours of electric rake rock only
