“地质与勘探”1959年第11期上发表的“鑽孔补矿填充封孔的方法”一文,比較簡明地阐述了填充封孔,投入偏心管及操作注意事項等具体方法,对鑽探施工中的导斜补矿,有一定的指导作用。但根据我队五年多來在晉中汾西一带煤田勘探中多次人工导斜补矿的經驗,觉得文中所提尚有些不够完善之处,特提出如下一点个人见解和几項补充意见,与同志們商榷。一、填充封孔文章指出……“将长約0.3公尺大于跑矿井径的草袋子塞入井口,降下鑽具(代取粉管接手)慢慢送下至跑矿下部10米的孔深处即停止,升上鑽具,再降下鑽杆到距填充草袋上部3—4米处,关合立轴,向井内送冲洗液,待冲洗液循环即开车廻转鑽具,从井口連續投入平均直径40—50毫米较软圆的石子……”。
“Geology and Exploration” No. 11 in 1959 on the published “drilling fill fill sealing method,” a text, a more concise exposition of filling sealing, eccentric tube investment and operational considerations and other specific methods for drilling construction Guide oblique complement mine, there is a guiding role. However, according to my team’s experience in the field exploration of coalfields in Fenxi, Jinzhong, for more than five years, I feel that there are still some imperfections in the exploration of coalfields. I hereby put forward the following personal opinions and some supplementary opinions, Discuss with Comrades First, the filling of sealing articles pointed out that “... will be about 0.3 meters longer than the diameter of the running mine bag into the wellhead, lowering the drill (take the pink tube take over) to the lower runner 10 meters deep hole At the stop, raise the drilling tool, and then lower the drill pipe to the upper part of the bag filled with grass bag 3-4 meters, close the vertical axis, to send fluid to the well, to be flushing fluid that is driving the car 迴 turn drill, continuous input from the wellhead The average diameter of 40-50 mm softer round stones ... ”.
