综合机械化采煤,在我国的煤炭生产中已显示出它的巨大优越性,它是我国煤炭开采技术的发展方向。但综采设备投资费用高则成为发展综采的最大障碍。一套国产综采设备费用,一般需要700万元左右。而一套引进的综采设备又比国产的设备费用高近一倍,而且引进的综采设备的生产能力都偏大,它们和我国大多数煤矿的实际生产系统能力不相匹配,在各方面造成了一些浪费。
Comprehensive mechanized mining, coal production in our country has shown its great superiority, it is China’s coal mining technology development direction. However, the high investment cost of fully mechanized mining equipment has become the biggest obstacle to the development of fully mechanized mining. A set of domestic fully mechanized mining equipment costs, generally need 7000000 yuan or so. And a set of imported fully mechanized mining equipment than the cost of nearly double the domestic equipment, and the introduction of fully mechanized mining equipment production capacity is too large, and most of our coal production capacity does not match the actual system, in all aspects Caused some waste.
