我队山地工作中的手掘坑井通风问题，一直没有得到有效解决。去年六月在龙场矿区组织千米井时，就因通风设备赶不上，使30个浅井工作面工作到第十天时有一半被迫停工。这一教训激起了大夥猛攻通风关的斗志。六月下旬，矿区全体职工在党支部领导下，投入了自力更生，大造鼓风机的战斗。经过二十多天奋战，终于克服了重重困难，用本料、钢钎、土弹子盘、废铁片等，制成了10台三用单人脚踏鼓风机。经现场使用，30—50米坑道，每次爆破用2—3公斤炸药，20多分钟就可把炮烟耕完。
The problem of ventilating hand mines in our team’s mountain work has not been effectively solved. When the kilometers of wells were organized in the Longchang Mining Area in June last year, due to the lack of ventilation equipment, half of the 30 shallow wells were forced to stop working on the tenth day. This lesson aroused everyone’s fierce fighting spirit. In late June, all workers in the mining area under the leadership of the Party branch invested in self-reliance and created a blower. After more than 20 days of hard work, it finally overcame many difficulties. With this material, steel brazing, soil marble plates, scrap iron plates, etc., 10 sets of three-person single pedal blowers were made. After field use, the 30-50m tunnel uses 2-3kg of explosives for blasting each time, and more than 20 minutes can be used to plough the gunfire.
