我队一分队白水普查組在四月高产月里,在槽探施工中試驗及使用了冲钎法,結果以48个工班,完成了1016.3M~3的任务,(三个人工作了十六天,其中大雨天又占了三天半)平均工班效达到21.2M~3,现将結果整理于后: 一、地质条件:(白水)岩层为风化花崗岩,壤土状,按地質部岩石分級标准为1～2級,槽深一般为1.5米,槽长20～60米,槽宽为1～1.2米,地形为土丘形,矿脉风化程度相当于围岩。二、使用工具:(1)冲钎,直径为5/8″六稜实心炭素鋼钎,最长为1.8米,掏勺(即坑道打眼用的砲扒子),小木桶,打水眼盛水用。(2)一般槽探出土用工具,铁鍬、土箕、铁耙。(3)修理规格用洋鎬、鋤头。
During the high-yielding month of April, a team of white water census team tested and used punching and brazing methods in slot drilling, resulting in 48 work shifts, completing 1016.3 M ~ 3 tasks (three of them worked for 16 Day, of which the rainy day accounted for three days and a half) the average work efficiency to 21.2M ~ 3, the results are arranged in the future: First, the geological conditions: (white water) rock is weathered granite, loamy soil, according to the Ministry of Geology rock grading The standard is 1 ~ 2 grades, the groove depth is generally 1.5 meters, the groove length is 20 ~ 60 meters, the groove width is 1 ~ 1.2 meters, the terrain is mound shape, the vein weathering degree is equivalent to the surrounding rock. Second, the use of tools: (1) Chong brazing, diameter of 5/8 "hexagonal solid carbon steel brazing, up to 1.8 meters, digging spoon (that is, Water (2) General trenches out of soil tools, shovels, soil, iron rake (3) Repair specifications Yang pick, hoe.
