煤矿

But there are some elusively essential problems for GIS applied in mine field.

但是目前煤矿领域的地理信息系统有些难以解决的本质问题，主要是对地下三维地质体的数学建模没有很好的解决办法。

In the construction of Ⅲ101 roadway in Haizi Coalmine,the blasting result and the embrasure utilization ratio have a good advance by using the wedge cutting and deep hole blasting technology,and produce substantial economical benefit.

在淮北矿业集团海孜煤矿Ⅲ101回风巷中硬岩巷道掘进施工中，通过改变过去的浅孔多循环爆破作业方式，采用楔形掏槽和中深孔爆破技术，提高了炮眼利用率，爆破效果有了很大提高，产生相当可观的经济效益。

In this about design the pump of the emulsification,the importance of the reason is that it has extensive use at the coal mine industry.

此次设计乳化液泵主要是因为它在煤矿工业上有主要的应用。

It was travelling within Mexico, en route from an explosives plant to a mine, with a cargo of 25 tons of ammonium nitrate. The wreckage exploded in a giant fireball, killing more than 30 people.

这辆卡车正载着25吨硝酸铵行驶在墨西哥境内一个炸药厂通往一个煤矿的路上，爆炸形成了一个巨大的火球，造成至少30人死亡。

A pumping-engine was erected there by Robert Hawthorn, now the Duke's engineer at Walbottle ; and old Stephenson went to work it as fireman, his son George acting as the engineman or plugman.

罗伯特·霍桑当时在瓦堡特尔已被公爵提升为工程师，他在纽布恩煤矿搭建了水泵机，老罗伯特·斯蒂芬森担任司炉，他的儿子乔治当了一名机械师或电源操作工。

In the hands of Watt, the instrument maker, who devoted almost a life to the subject, the condensing engine acquired gigantic strength; and George Stephenson, the colliery engineman, was certainly not the least of those who have assisted to bring the high- pressure engine to its present power.

煤矿机械师乔治·斯蒂芬森当然也只是那些曾经努力使高压力发动机获得目前的力量的人员之一。海纳百川，有容乃大；壁立千仞，无欲则刚！

The communication subsystem was designed by VB, adopted duplex communication mode, data format of data frame, and timed detecting mode, which enhanced capability of whole communication system, provided a high-efficiency and credible communication platform for monitoring system of gas in mine.

该通信子系统采用VB设计，利用双向通信方式和数据帧的数据格式以及定时探测的方式，有效地提高了通信系统的性能，为煤矿瓦斯监管系统提供了一个高效可靠的通信平台。

The emulations and experimental results indicate that the theoretical model combined the neural network and genetic algorithm not only can conquer the disadvantage, which network is prone to enmesh the partial minimal error, but also utilize the powerful artificial intelligence of neural network.; This model provides a new method and idea for the monitor systems management, meanwhile it also offer a new method for solving the problems of the undetermined information processing; This model has powerful studying function, high accuracy, and strong practicability, so it has promoted value.

仿真及实验结果表明：由于此数学模型是将神经网络和遗传算法相结合应用在井下的监控系统中，因此即克服了神经网络容易陷入局部最小误差的缺点，又利用了神经网络本身强大的人工智能；该模型不仅为煤矿监控系统管理提供了一种新方法和新思路，同时也为解决不确定性信息处理问题提供了一种新的尝试和手段；该模型学习功能强大，精度较高，实用性强，具有很好的推广价值。

According to"Coal mine Safety regulation"the request,this article mainly analyzes the relation between the hoist's brake torque and brake deceleration in the equipollent tail rope promotion system,produced the relational curve of deceleration and the gravity characteristic coefficient and the braking moment multiple.

根据《煤矿安全规程》的要求，通过对在等重尾绳提升系统中制动力矩与制动减速度关系的分析，给出了减速度与重力特性系数和制动力矩倍数的关系曲线。

After the coal mine mine shaft electric cable damage causes,receives an elective shock the accident and fire the gas,the coal dust equipollent especially big accident occurrence more over the electric cable fund invests in a big way.

煤矿井下电缆损伤后，引起触电事故和火灾、瓦斯、煤尘等重特大事故的发生，而且电缆资金投入大。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
