文中论述了国内外煤层锚杆支护技术的发展动向及概况;介绍了国内外一些可借鉴的煤层锚杆支护技术经验。由于煤层地质构造复杂,煤厚变化大等难采煤层条件在水采矿区占90%以上,故水采矿井煤巷钻杆支护技术发展缓慢。随着我国煤巷锚杆支护技术的大力推广普及,煤炭工业部确定了“九五”期间要积极引进、消化、推广钻杆支护技术的战略方针。在此形势下,我国水采矿井应抓住时机,大力加快发展煤巷锚杆支护技术,以适应水采矿井在市场经济机制运转下生产发展的需要。
This paper discusses the development trends and general situation of coal seam bolt support technology at home and abroad. Some experiences of coal seam bolt support technology at home and abroad are introduced. Due to the complex geological structure of the coal seam and the large variation of coal thickness, the conditions of hard-to-be-taken coal seams account for more than 90% in the water mining area. Therefore, the technology of drill pipe support in coal mining roadways has been developing slowly. With the vigorous promotion and popularization of bolt support technology for coal roadway in China, the Ministry of Coal Industry has set forth the strategic guideline of actively introducing, digesting and popularizing drill pipe support technology during the Ninth Five-year Plan period. Under this situation, China’s water mining wells should seize the opportunity to vigorously speed up the development of coal seam bolting technology to meet the needs of water mining wells in the production and development of market economy mechanism operation.
