煤炭资源勘查误差理论研究

对煤炭资源勘查资源量与客观物质量之间差值的误差理论探讨,提出误差由真值误差、系统误差和离差3个基本部分组成,其中真值误差是不可消除的观测误差、系统误差是控制网度所决定的准确度标准、而离差是由地质构造及矿床形态的多解性产生的资源量波动。在此基础上,构筑了一个关于误差的数学模型,最后应用误差理论对现行勘查工作中常见的错误进行分析,并就如何避免错误及减少误差提出了见解。

On the Error Theory of Prospecting Coal Resources

The paper makes an academic approach of the difference between the surveying coal resources and the quantity of actual materials.It is considered that the errors compose of the true value error,systematic error and dispersion.The true value error is the unsuppressible observational error.The systematic error results from the accuracy standard controlled by the exploration control network.The dispersion stands for the variational quantity of mineral resources aroused by ambiguous explanation of geological structures and ore deposit shapes.One mathematic model of the errors is put forward herein according to the research results.The common inaccuracy is also under discussion of prospecting coals by the error theory and some proposals about preventing mistakes and decreasing errors are presented in the paper.
