In 2000,the area below 400 meters was also watershed,mining sites and settlements,the proportion of both unutilized land below 400 meters and woodland between 400 meters and 800 meters raised a little,it showed that most woodland transform into the other types of land use in low altitude area,however,most unutilized land and the other types of land use transform into woodland in low and mediad altitude area,and the changes in woodland had metastatic trends in low and middle altitude area in the years from 1988 to 2000.The area proportion between 400 meters and 800 meters raised a lot in mining sites and settlements,the total distributed area on woodland had a trend of rising,while the distribution in pasture had a trend of decreasing.

在2000年，400m区域以下依然是水域和居民点及工矿用地，未利用地比例在400m以下有所上升而林地比例在400m～800m有所上升，表明在1994年至2000年间，低海拔地区许多林地转化为其他土地利用类型，而在中低海拔地区大量的未利用地和其他土地利用类型转化为林地，林地的变化有向中低海拔转移的趋势。2006年居民点及工矿用地在400m至800m区域面积比例增加，林地类型分布区域整体呈上升的趋势，草地分布区域呈下降的趋势。

The essence is how to use the mine microseism, under the unchanged mining intensity, which occurs upon accumulation of the respective low stresses, to predict the next extremum mine microseism due to occur during the stress mining environment classified by the increased isostress gradient instead of a period divided by the human experience.

其实质是在开采强度保持不变的前提下，用各自较低应力环境累计发生的矿山微震，预测下一个按等应力梯度增高的应力强度环境开采期间将要发生的极值矿山微震，而不是人为经验划定的某一时段。

The company was founded in 2007, mainly engaged in molybdenum concentrate, molybdenum trioxide, molybdenum calcium, molybdenum iron, production and operation activities; lead, zinc, copper, germanium ore, iron ore and other products, building materials sales business, business own mining resources, with mining, elections, rule of production capacity, the company has a strong, strong technical force, strict production quality.

Firstly, the stope vacancy was monitored using CMS, taking cavity measured data as foundation, cavity three-dimensional model of the stope opening was created using Surpac software and gain the stope three-dimensional configuration and the actual boundary accurately. Then, the stope designed model and ore-rock interface digital terrain model were established according to the stope design material. Finally, using ore-rock interface DTM to cut cavity model or through Boolean calculation among the models, ore remains, mining total volume, mullock, backfilling, pure ore and dilution rate of stope N3-4 were calculated accurately, thus the large-scale stope mining index visible calculation was realized effectively.

采用CMS探测三维采场空区，以空区实测数据为基础运用Surpac构建采空区三维可视化模型，获取采场空区的三维形态和实际边界；运用采场设计资料，建立采场回采设计模型及矿岩边界模型，通过模型间的布尔运算，计算出采场存留矿量、回采总体积、采下废石量、采下充填体量、采下纯矿石量、回采总量及回采贫化率等，从而有效地实现了大规模采场回采指标的可视化计算。
