作者通过对采煤成本的分析,推导出综采工作面经济上最佳长度的计算公式,并列出了工作面连续推进方向长度与搬家倒面费和采准巷道掘进费的函数关系式。然后根据我国当前采煤方法、设备性能和设备价格、工人工资、工人操作和管理水平等条件,应用这些公式,确定了综采工作面最佳长度和连续推进方向合理长度。
Based on the analysis of coal mining cost, the author derives the formula for calculating the optimal economic length of fully mechanized coal mining face, and lists the function of the continuous propulsion direction length and the moving cost and the roadway driving cost. Then according to the current coal mining methods, equipment performance and equipment prices, workers ’wages, workers’ operation and management level and other conditions, the optimal length of the fully mechanized coal mining face and the reasonable length of the continuous propulsion direction are determined.
