摘要
根据土城矿综采工作面和高档普采工作面的实际生产情况作了统计，并运用技术经济和数理统计的有关知识和方法，系统地计算并分析了综采面和高档普采面的成本、产量及其连续推进长度之间的关系，从而为该矿正确选择采煤工艺提供了依据。
Collected the real information of production about the full mechanized working faces and super conventional machine working faces in Tucheng Mine.Applying the knowledge and the methods of the technology economics and the statistics the writers systemationlly calculated and studied the relationships of the cost the output and the continued progress length of these working faces.And therefore,we can correctly select the coal extraction technology and method of these working faces according to their relationships in Tucheng Mine.
