一、前言 近年来随着技术的不断进步,以及微电子技术的大量应用,使井下采煤获得了迅速发展。设备设计上的改进,使用上的革新,设备状况及使用性能的监控,以及全矿范围数据的采集和电子通讯技术的发展,都使井下开采的工效及安全性得到很大提高。 二、采煤技术的发展与动向 现在世界各国都在积极采用长壁后退式开采法,同时重点开发高效、安全、低耗的开采设备,澳大利亚正重点发展带有整个顶板装置的井巷开拓设备,高产量的长壁后退开采设备及机械化煤柱回采设备和长壁采煤设备的发展方向是要提高它的可靠性,改善其使用性 I. Introduction In recent years, with the continuous improvement of technology and the large-scale application of microelectronic technology, the underground coal mining has gained rapid development. Equipment design improvements, the use of innovation, equipment status and the use of performance monitoring, as well as the whole range of data collection and electronic communications technology development, make underground mining efficiency and safety has been greatly improved. Second, the development and trend of coal mining technology All countries in the world are now actively using the longwall back-mining method, while focusing on the development of efficient, safe, low-cost mining equipment, Australia is focusing on the development of the entire roof with the well equipment to open up equipment , High-yielding longwall back-mining equipment and mechanized coal pillar mining equipment and longwall mining equipment development direction is to improve its reliability and improve its usability
