我們在导斜补矿中所採用的投石子填充封孔的方法效果良好,操作簡单,化費时间少,茲作如下介紹,仅供参考一、填充封孔首先須計划好补矿填充位置的深度及导斜补矿鑽程。再将长約0.3公尺大于跑矿井徑的草袋子塞入井口,降下鑽具(代取粉管接手)慢慢送下,至跑矿下部10公尺的孔深处,即应停止昇上鑽具。再降下鑽桿 We are used in the guide oblique fill mine pitching plugging method works well, simple operation, less time-consuming costs, it is made as follows, for reference only First, fill the first hole must be planted filling filling position Depth and guide oblique complement mine drilling. And then about 0.3 meters longer than the diameter of the running mine bag grass into the wellhead, lowering the drill (take the pink tube take over) slowly sent to the lower runner 10 meters deep hole, it should stop rising Drilling tools. Lower the drill pipe again
