The function of SD precision

SD law not only can be used as reserves accuracy degree of precision measurement, but also can be used as quantitative perspective from the basis of the degree of investigation. China has promulgated linked to the world classification of mineral resources in the new standard, according to the out of the different degree of precision exploration will be divided into geological reliability of the four categories: The four types of Proven, control, the inference and forecasts. According to the category, we can say this: SD accuracy of the size, can be divided into non-linear in the range of four, as a geological reliability of the quantitative characterization of the scale.

Measurement accuracy is SD reserves true value of the interval of four standards. As long as that value accuracy, it can reduce the risk of blindness.

SD precision forecasting accuracy is a district that interval of the range the smaller the scope, the greater the accuracy and small risk. But the need for a higher degree of inspection interval can narrow the scope. In fact, the exploration stage no need to require high precision small-scale, as long as the corresponding meet the requirements of various departments. Therefore, SD accuracy can guide the work of the inspection process. The deposit users requiring high precision, the scope of smaller is better. It can reduce the risk of strengthening the plan and improve the social and economic benefits.
