一怎样开始的(一)以前的情况第三铜矿自五○年以来一向未打水眼,支架子凿岩也仅是在领导的号召下,在本坑断续的实行了几次而已。直到第三季度才获得了一些成绩,初步的巩固了一部分,但多数仍未采用支架子的辨法。有的打了两个眼,稍遇故障或稍不顺手就卸下来抱着打了。这样一直延至今年四月。造成这种情况的主要原因有以下几点: 1、领导上对支架子凿岩只做了一般的号召,缺乏具体的布置和领导,缺乏坚持这一工作的思想。

How to Start (a) The Previous Situation The No.3 copper mine has been inundated for a long time since 1950, and the support drill was only carried out several times intermittently in this pit under the leadership’s call. Some achievements were not achieved until the third quarter, with some consolidating initially, but most still did not adopt the bracketing method. Some hit the two eyes, a little trouble or a little unsafe to remove and hold hit. This has been extended until April this year. The main reasons for this situation are the following: 1, the leadership of the holder of the drill only made a general call, the lack of specific arrangements and leadership, the lack of adherence to the idea of ​​this work.
