矿井

According to the source,character and using intention,as well as the site rules of Pingmei Group mine drainage,different water treatment technologies are adopted to clean the wastewater and at the same time a special water supply system is selected,which transports cleaned water dividedly on the whole and collectedly in the part,so the water resource is not only fully utilized,the environment is protected,but also the cost is lowest.

针对这种同一矿区既水满为患，又水贵如油的局面，为治理污染改善环境，根据矿井水的性质和特点，开展综合利用研究是非常必要的。1矿井排水水质特点根据集团各矿井排水的

We developed two kinds of new products for low-power and high-resolution mine shallow seismograph, mine geology detector and mine tunnel predictor. By field experimental verification, they can solve effectively the detecting problem of small geological structure and coal seam thickness around underground coal mine tunnel. Their performance and function of reached or exceeded the level of domestic similar products, and their power consumption (≤4W) is lower than the advanced high-resolution shallow seismographs at home and abroad.

开发出两款低功耗高分辨率矿井浅层地震仪产品——矿井地质探测仪和矿井巷道超前探测仪，通过现场试验验证，其可有效地解决煤矿井下巷道四周浅层地质小构造勘探和煤层厚度探测问题，仪器性能和功能达到或超过国内同类产品水平，且仪器的功耗(≤4W)小于国内外先进的高分辨率浅层地震仪产品

Ventilating system is an important part of production system, providing guarantee for mine to produce safely of mine.

矿井通风系统是矿井生产的重要组成部分，是矿井安全生产的保障体系。

According to the water quality characteristics of mine water in Shanxi province experiment is made to study to removal effect of sulfate radical by coagulative adsorption of mine water .

针对山西省煤矿矿井水的水质特性，研究通过混凝吸附作用对矿井水中硫酸根的去除效果，通过实验，发现在pH=7~8时，采用Ca2+PAC+少量PAM的药剂投加方式，对矿井水中硫酸根的混凝吸附去除效果较好。

Grouting in the around of infalling boundary and informing wall to prevent water based on clear knowning the condition of geology and hydrology. This method not only assure the safety of production but also protect the water resources around the colliery.

注浆封堵技术是在查清矿井水文地质条件的基础上，通过对进水区边界实施注浆工程，形成人为的挡水墙，从而阻断底板水的涌入，既解放了受水威胁的煤层又保证了矿井的安全生产，同时也保护了矿井周围水资源。

The resistance measuration on ventilation system of mine is an important content of ventilation resistance technology management.

矿井通风阻力测定是通风技术管理工作的重要内容之一，掌握矿井通风系统阻力的分布情况对矿井通风日常安全管理十分重要。

Mine mine mine ventilation is to protect the safety of one of the most important technical means.

矿井通风是保障矿井矿井安全的最主要技术手段之一。

forecast brust water ; mine resistivity tomography ; mine transient electromagnetic method ; radio penetration method

因此，开展矿井水文地质基础理论、矿井水害预测技术及矿井防治水措施研究，已成为目

According to the underground pressure theory which takes stratum movement as key matter, the reactivating mechanical mechanism of a fault in mining floor under the action of underground pressure, and the mechanism of the interaction between pressure water and rock during the fault reactivation are studied.

基于大量的煤矿井突水案例，总结了中国煤矿井突水的一般规律及肥城煤田矿井突水的特点。根据&以岩层运动为中心&的矿山压力控制理论，研究了采场断层在矿山压力作用下活化的力学机制，以及断层活化过程中承压水和岩石相互作用的机理。

Rockburst is a mine seism that is caused to happen by mining, it is one of natural calamities. It is a dynamic phenomenon, the coal and rock mass or fault in high stress area releases a large of energy when it is disturbed and instability destroy instantaneously, and its characteristic is volcanic shake and explosive destroy.

冲击地压是采矿诱发的矿井地震，是矿井的一大自然灾害，是指矿井高应力区内煤体、岩体及断层在受外界扰动瞬间失稳破坏时，释放出很大能量而引起的以猛烈震动和爆发式破坏为特征的矿山动力现象。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
