(一)單人双机需要具备的条件——这些条件以降低凿岩工劳动强度为目的: 1.工作面高要在2.1—2.2公尺內,不能太高或太低,以符合套一号钎子的要求。 1.4公尺(机器長)+[0.8公尺(一号钎桿長)-0.2公尺(产子控制器深)]=2公尺+机器上一号钎子后長度。 2.炮眼深度以1.4公尺为好,——阶梯高度1.4公尺。 (1)只套三次钎子就打完一眼; (2)第三号钎子長1.6公尺岩工手抓在中间就可套上; (
(A) Single and double need to have the conditions - these conditions in order to reduce the labor intensity of the rock drill for the purpose: 1. Face height should be 2.1-2.2 meters, not too high or too low to meet the set of a Number of solder requirements. 1.4 meters (machine length) + [0.8 meters (number one drill rod length) -0.2 meters (birth controller depth)] = 2 meters + 2. The hole depth of 1.4 meters is good, - ladder height of 1.4 meters. (1) Only three shots of brazing filler metal are taken at a glance; (2)
