With the rapid development of modern science and technology, the global economic integration graually deepens, English for science and technology(EST) will be attached greater importance and concern in scientific and linguistic fields. Many countries in the world, including China, have established research centers of EST, have also set up this major or department in universities, specializing in research, teaching of EST and raising talents in this field. This fully shows that the rapid development of China's science and technology, the positive cycle of economy as well as the world's political, economic, scientific and technological activities have an increasing need for EST. From the application point of view, scientific and technical personnel need to master the linguistic features of EST, such as glossary, grammar and sentence structure.

Coal mine main fan is one of the largest-power-consuming facilities among various electrical and mechanical equipments, its power consumption usually accounts for 20% ~ 30% of the total. If a few percentage points can be lowered in its energy consumption, energy efficiency will be very substantial. One main reason for the main fan's high power consumption is its overall low efficiency. After a long time operation, most of the coal mine fans' impeller, intake air box, air inlet and chassis have a serious corrosion, which is a main threat to the safe operation of fans, and also increases the running resistance, less efficiency, thus can not meet the actual on-site demand. Therefore, performance optimization of the fan to reduce power consumption is imperative. A set of technical improvement program that focuses on saving energy and increasing efficiency is designed on the basis of surface anti-corrosion.
