Glauberite mining company located in the base of raw materials, ores rich, high grade, to meet the annual production capacity of 200,000 tons of raw material production facilities demand, mining technology and processing of production to achieve the advanced level in the same industry and has an annual output value of 60 million yuan.

公司矿区地处钙芒硝原料基地，矿石蕴藏丰富、品位高，能满足年产20万吨生产装置的原料需求，开采工艺及加工生产达到同行业先进水平，年产值达6000万元。

The invention began in 2000, and was respectively promoted and applied in the ground mining of Yuncheng mirabilite mine and Sichuan glauberite mine. It added RMB 227.5 million of output value, increased revenues and cut expenditures of RMB 142 million.

本发明于2000年始，分别推广应用于运城芒硝矿及四川钙芒硝矿的地面开采，新增产值2.275亿元，增收节支1.42亿元。

It shows that the particle vibration velocity is related to the maximum single sound charge,distance from the blasting point uo the measured point,types of explosive and blocking condition.While transforming opencast mining into underground mining,if a goave is filled up with gangues,the surface rock mass of slope ca...

在露天转地下开采时，如果对采空区充填废石，不仅可以使边坡表面岩体处于有利的三向受力状态，回填废石体还起到了爆破减震作用，同时还有明显的高频滤波作用，有利于保持地下巷道的稳定性。

The study provides the scientific foundation for applying injecting the grouts into the bed separated zone of overlying strata to control subsidence.

As a result of the speedy development of the cities, the demands of stone material become more and more. Many hypaethral quarries have been built because of this, but people neglect the ecological and environmental impact brought by opencast working. And the prevention and cure steps that do isn't arrive at the goal of zoology renew.

摘要由于城市发展迅速，对石料的需求也越来越多，许多的露天采石场因此建立起来，但是他们却忽略了露天开采所带来的一系列生态环境影响，而且所做的防治措施远没有达到生态恢复的目标。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
