工作矿井

I've quite become used to working in the pit.

我已经很习惯在矿井里工作的。

Boof hates digging and is put to work dragging the trolley of rubble through the mine shaft.

Boof不喜欢挖掘且作透过矿井的手推车拖碎石的工作。

One day Boof, too tired to work any more, grasps one of the heavy wooden beams that support the roof shaft, bringing the mine in on top of the seven dogs.

有一天，Boof太疲倦以致於无法工作，它抓住支撑矿井屋顶其中之一沉重的木制梁柱，把矿带进来於7条狗的上方。

Albrecht Durer won the toss and went off to Nuremberg.

而他的兄弟阿尔伯特则下到危险的矿井里工作，并以此来资助他的兄弟完成了四年的学业。

The viewpoint about how to ensure safety production is expatiated from the aspect of safety management. Several questions that should be solved in mine safety management are discussed particularly firstly in this paper. In second part, with the principle of accident tree, some representative cases in one mine are analyzed, and more thirty laws are educed about the time, places and working procedure that easily make accidents happen, and the conclusion is confirmed by a lot of accident cases happened in our country. In third part, the Five Elements about mine safety are analyzed, they are: the basis is quality standardization, furnishment should be mechanised, management should be strictly based on laws, prevention should be ahead of time, the emphasis is group construction.

本文从安全管理的角度阐述如何保证安全生产的观点，首先详细论述了煤矿安全工作中应解决的几个认识问题；第二部分通过事故树原理分析，就典型矿井的案例揭示了煤矿容易发生事故的时间、地点、生产工序、人员等三十多条规律，总结和统计全国煤矿事故，进一步印证了这些观点的正确性；第三部分分析了煤矿安全的"五要素"，即基础是质量标准化、装备是机械化、管理是依法从严，预防就是超前，重点就是班组建设。

Work is to be done at the ground level i.e.

工作是在地面，并非在矿井里面。

This product is applicable to coal mine where has explosible dangerous gas and coal dust,It is used for controlling direct starting stop and reversion of three-phase squierrel cage type asynchronous motor whose rated current up to 400A in system of AC50Hz rated voltage 1140V or 660V, Meanwhile it protects the electromotor and relative circuit, The starter can be combined with firedamp sensor and used to test the consistency of mining working area,the starter will trip when it exceed the limit ;adopt intrinsic safety type circuit for the control circuit; possess the function of local control and remote control by single set and multi sets procedure control; display working voltage current and gas consistency can remember fault parameter

该产品适用于具有爆炸性危险气体和煤尘的矿井中，在交流50Hz，额定电压为1140V或660V ，控制额定电流只400A的三相鼠笼式异步电动机的直接起动，停止及反转，同时对电动机及有关电路进行保护，起动器可与甲烷传感器相连接用于检测才掘工作面的甲烷浓度，当其超限时起动器跳闸；控制电路采用本安型电路；具备单台就地控制与远方控制及多台程序控制功能，能显示工作电压、电流、瓦斯浓度，并能记忆故障参数。

As the introduction of synthetical techniques and the development of fully mechanised coal mining working faces to be overlength and high efficient, new demands are engendered.

由于综采技术的引进和综采工作面向超长高效方向的发展，对矿井防灭火工作提出了新的要求。

When mine pit tunneling tunnel, breathes the fresh air for the supplies staff, the noxious gas which the dilution tunneling working surface's gas and produces, the mine dust, the creation good working condition, must carry on to the tunneling working surface ventilates.

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
