摘要 以金山店铁矿和程潮铁矿部分主要外委井巷工程单价为样本,依据Bootstrap自助法对样本数据进行再抽样,计算出样本均值的相对频率分布大体呈正态分布,并结合国家基础定额对样本单价进行分析,得到金山店铁矿的工程单价定价与定额标准偏差较大,程潮铁矿定价与定额标准接近,同时考虑矿山地质条件以及其他影响工程单价定价因素,对样本单价合理性进行探讨。结果表明在合同制采矿条件下,工程单价报价大体呈正态分布是合理的;工程单价的合理制定不能仅仅依据定额标准和市场因素,更要充分考虑矿山工程自身特殊因素。 The research has cited the engineering unit price of the main sinking and driving of Jinshandian Iron Mine and Chengchao Iron Mine as the case study. It was found that the relative frequency distribution of mean unit price was normal distribution by Bootstrap method. While, the pricing of unit price of Jinshandian Iron Mine was deviation in the national quota, but Chengchao Iron Mine was close to the national quota. And then the rationality of the sample price was discussed combined with the geological conditions of the mine and other factors influencing the unit price of the project. The result showed that the normal distribution of the unit price was reasonable in contract-based mining; and the formulation of unit price not only relied on the quota standard and market factors, but also depended on the special factors of mine engineering.
