煤矿巷道掘进施工及顶板支护技术研究

Construction of Coal Mine Roadway Excavation and Roof Support Technology

煤矿巷道掘进施工和顶板支护是煤矿开采中的重要环节。通过研究巷道掘进施工技术和顶板支护技术,探讨了其重要性、影响因素以及现有的研究成果。在巷道掘进施工中,综合机械化掘进技术和大断面连续采煤机掘进技术是主要研究方向,而在顶板支护方面,通常采用锚杆支护、棚式支护、临时支护工艺和预留煤柱支护等技术。通过对这些技术进行研究和应用,可以提高煤矿生产的效率和安全性。

The excavation construction and roof support of coal mine roadway s are important links in coal mining.The importance,influencing factors and the existing research results were discussed by studying the roadway driving construction technology and roof support technology.In roadway excavation construction,fully mechanized excavation and large section continuous shearer excavation technology are the main research directions,while in roof support,bolt support,shed support,temporary support technology and reserved coal pillar support are usually adopted.Through the research and application of these technologies,the efficiency and safety of coal mine production can be improved.
