我国煤矿采掘机械制造技术水平的进展及分析

摘要

The level of mining machinary manufacture in China has made a great progress, by investing, researching and developing during ＂the Tenth Five-Year Plan＂ and ＂Eleventh Five-Year Plan＂. The manufacture technology of shearer, scraper conveyor, roadheader and hydraulic support has approached the world＇ s advanced level. Our country has become a major one of manufacturing coal mine machine. However, the manufacture technologies of key elements and components fall behind the advanced international enterprise. The core elements and components are almost depending on imported products. The development of complete machine and parts are uneven. This phenomenon calls great attention to the whole industry and related departments.%经过“十五”、“十一五”的投入和科研攻关，我国煤矿井下采掘机械关键设备，采煤机、掘进机、刮板输送机和液压支架的生产制造水平不断取得突破，整机制造技术已逼近世界先进水平，成为煤机生产制造大国。然而，其关键元部件的发展速度较为滞后，为整机配套的某些核心元部件仍依赖进口，这种情况有必要引起整个煤机行业及国家相关部门的关注和重视。
