我公司三队山地工程队,推行了兄弟队的先进爆破经验——一字形,阶梯形,人字形,一边推,无眼爆破等方法,均不同程度的提高了爆破效率。他们在总结兄弟队创造的各种先进爆破经验的基础上,于2月28日创造试行了“探槽定向抛掷爆破法”,创我公司槽探人/日生产1323m~3的高产记录。所创“漏斗形定向抛掷爆破法”操作方法如下:一、根据地质方面所提出的要求,他们在该施工地区所打的炮眼深浅不一,从0.50m 到1.00m、1.50m,炮眼方向和间距如图示。
The three teams of our company’s mountain engineering team have implemented the advanced blasting experience of the brothers - one-letter, step-like, herringbone, push-side, and no-eye blasting, which have improved blasting efficiency to varying degrees. On the basis of summing up the various advanced blasting experiences created by the brothers, they created the “trough-oriented throwing blasting method” on February 28th to create a high-yield record of 1,323m~3 in production of our company. The “funnel-oriented directional blasting method” was created as follows: 1. According to the geological requirements, they had different shot holes in the construction area, ranging from 0.50m to 1.00m, 1.50m, and the direction of the borehole. Spacing as shown.
