冬天快来了,砖瓦要冬季生产,首先必须储备大量粘土,因此提高采土效率,是实现砖瓦冬季生产关键之一.张家口市第一、二砖瓦厂职工,在大搞技术革新、技术革命运动中,采用爆破方法代替手工采土获得成功,收到了显著效果: 1.提高采土效率,节省大批劳力.过去手工采土每个工人平均每日采土6立方米左右,采用爆破采土,平均每人每日达到48立方米,比手工采土提高效率8倍多. In winter, when bricks and tiles are to be produced in winter, they must first store a large amount of clay. Therefore, improving the efficiency of earth mining is one of the key factors for the production of bricks in winter. The workers of the first and second brick and tile factories in Zhangjiakou City are engaged in technological innovations. In the technological revolutionary movement, the blasting method was used instead of manual soil-picking to achieve success and received significant results: 1. Increased soil-efficiency and a large amount of labor. In the past, each worker manually-soiled an average of about 6 cubic meters of earth and used blasting. The average amount of earth is 48 cubic meters per person per day, which is more than 8 times more efficient than manual mining.
