一、概述 三河尖矿主井井筒荒径6.4米,净径为5.6米。在井筒垂深387.3～459.4米井段的开凿施工中,采用了三个半月的FJD6型伞形钻架,配合YG80型导轨式凿岩机进行凿岩。实际循环46个,进尺76.3米,其劳动组织为四个专业班,即打眼放炮班、出矸喷射混凝土班、出矸班及出矸清底班。每天四班作业(循环作业图表见图1)。实行叫班制(滚班制),即不仅控制作业时间,而且要求每班按质、按量完成既定任务后才能升井下班,否则,要延长工作时间。这种劳动组织的优点是工作专业化,使技术得到不断地提高,人人都明确本班的任务,有利于循环的完成,有利于加快施工速度。
First, an overview Sanhejian Mine main shaft bore diameter of 6.4 meters, a net diameter of 5.6 meters. In the borehole 387.3 ~ 459.4 m deep well section of the construction, the use of three and a half months of FJD6-type umbrella drill rack, with YG80-type rock drill rig rock drill. The actual cycle of 46, footage of 76.3 meters, the labor organization for the four professional classes, that is, blasting blast class, a gang of refuse concrete squirting, gangue classes and gangue clearance classes. Four shifts per day (cycle chart in Figure 1). The implementation of the so-called class system (roll system), that is, not only control the job time, but also requires that each class by quality, by volume to complete the established tasks in order to work well, otherwise, to extend the working hours. The advantage of such labor organization is the specialization of work, the continuous improvement of technology, and the clear assignment of tasks for all to this task, which is conducive to the completion of the cycle and to the speeding up of construction.
