First, the overview Zheng wind shaft is Benxi Mining Caitun Coal Mine west of an air intake well, 826 meters deep, 6.2 meters in net diameter, anchor spray wall thickness of 0.2 meters. 82.5 meters above the wellbore is built by Benxi Mining Bureau, and the rest is contracted and constructed by our office (our contract with Caitun Coal Mine was contracted and constructed). I was building wells area on July 25, 1981 into point, began preparations for the well, September 1 formally dug well. By the end of 1981, a succession of 129.4 meters, an average of 32.35 meters into the month. In 1982, the management of construction technology was strengthened, the technical training of workers and staff was strengthened, the technical operation level of workers was enhanced, the regular circular operation was carried out, and the speed of establishing well was accelerated. In 1982, a total of 423.1 meters of wells were completed and three sections of 10m ~ 2 were constructed
