According to the dichotomy pixel Spatial Modeler modeling tool used to calculate the vegetation coverage in mining, use of non-supervised classification of vegetation coverage on the mining area classification, coloring, and finally come to mine the vegetation coverage in 1990-2000 category map, quantitative description of the Shanxi Province, 10 years of vegetation cover change: The region coverage to low, medium and high-based, the proportion remained almost unchanged, a significant increase in very low coverage, high coverage significantly decline.

根据像元二分法利用的建模工具Spatial Modeler计算出矿区的植被覆盖度，利用非监督分类方法对矿区的植被覆盖度进行分类、赋色，最后得出矿1990-2000年的植被覆盖度分类图，定量的说明了山西省10年间的植被覆盖变化情况：全区覆盖度以低、中和中高为主，所占比例几乎保持不变，极低覆盖度有明显增加，高覆盖度有明显下降。

Calculated the lower limit of abnormal after the plane through the delineation of the contour map of the occurrence and analysis of abnormal findings were as follows: work area on the lithology in terms of more or less divided into two parts, East and West, the western area for the low-resistivity, lithology is metamorphic carbonaceous sandstone or slate, for the emperor in eastern areas, lithology for granite and granite porphyry, quartz vein occurrence in eastern and more, these quartz veins is into the eastern part of the resistivity of the form of alternating high and low.

计算了异常下限值后，通过圈定了平面等值线图上的矿点异常和其它分析得到结论如下：工区就岩性而言大致划分为东西两部分，西部为低阻区，岩性为变质砂岩或炭质板岩，东部为高祖区，岩性为花岗岩及花岗斑岩，东部多赋存石英脉，这些石英脉是的东部电阻率成高低交替的形式。

ResultsAmong 8 cases,there were low or low slightly density as in 7 cases, single high slightly density tubercle as in 1 case, following these,there were multiple neoplasm metastasis of brain other sites in 2 cases, annular shape enhancement in 3 cases after contrast CT scanning, peripheral edema lightly as in 6 cases and no in 2 cases, suprasellar region, ambiens cisterna and corpora quadrigemina were compressed, transposited and distorted differentlly,and obturated or widened locally.
