贮带装置通过调整带式输送机的长度来减少因缩短输送带 　　煤炭是我国重要的基础能源和重要原料，煤炭工业的发展支撑了整个国民经济的快速发展。在矿井的生产过程中，大力发展综合机械化采掘技术，是增产增效推进煤矿建设，实现煤矿高产、高效、安全、洁净开采的基础，随着我国工业控制自动化技术的发展，煤矿机电自动化在矿上的应用越来越广泛，综合机械化采掘技术对建设现代化矿井，对现有工作条件低下的矿井进行技术改造，改造小煤矿、小煤窑，全面提高煤矿开采技术水平和资源采出率，起到了举足轻重的作用。 Coal is the important foundation energy and important raw material in our country, the development of coal industry to support the rapid development of the whole national economy. In mine production process, develop the comprehensive mechanized mining technology, is to increase efficiency to promote coal mine construction, realize the coal mine high yield, high efficiency, safe and clean production base, with the development of Chinas industrial control automation technology, coal mine mechanical and electrical automation application is more and more widely in the mine, comprehensive mechanized mining technology for construction of modern mine, the mine technical renovation of existing low working conditions, small coal mines, small mines, comprehensively improve the level of coal mining technology and resource recovery rate, has played a pivotal role. 　　1 煤矿综合机械化采煤主要设备状况 1 comprehensive mechanized coal mining of coal mine main equipment conditions 　　1.1采煤机 1.1 coal winning machine 　　采煤机是一个集机械、电气和液压为一体的大型复杂系统，是实现煤矿生产机械化和现代化的重要设备之一，主要分为滚筒式采煤机和刨煤机两种类型，当前我国煤矿采用可调高的双滚筒采煤机较多, 双滚筒采煤机的结构与动作原理和普采工作面所用的采煤机雷同, 不同的是其功率与生产能力等技术特征比普采工作面采煤机要大。 Coal winning machine is a collection of mechanical, electrical and hydraulic as one of the large complex system, is to realize the coal mine production mechanization and modernization of one of the important equipment, mainly divided into two types of cylinder mining machine and coal plough, current our country coal mine adopts adjustable double-drum shearer is more high, double drum structure and movement theory and the conventional working face of coal winning machine used in coal mining machine is the same, different is the power and capacity than conventional coal face mining technology characterist
