摘要
近年来,中国的煤炭工业发展迅速。但煤矿生产过程中的顶板事故频繁仍然是整个行业发展中较为突出的问题。因此,必须加强对煤矿顶板支护技术的开发和优化。只有不断地分析探索总结经验,改进提升掘进施工技术,加强顶板支护管理才能有效防止顶板事故的发生。论文对地下煤矿巷道顶板支护形式进行详细的分析,阐述了可能会造成顶层支护问题的不利因素及技术难点,并提出了有待改进的巷道顶板技术管理措施。
In recent years,China's coal industry has developed rapidly.But the frequent roof accidents in the process of coal mine production is still a more prominent problem in the development of the whole industry.Therefore,it is necessary to strengthen the development and optimization of coal mine roof support technology.Only by continuously analyzing,exploring and summing up experience,improving tunneling construction technology and strengthening roof support management can the occurrence of roof accidents be effectively prevented.This paper makes a detailed analysis of the roof support forms of underground coal mine roadway,expounds the disadvantageous factors and technical difficulties that may cause the problem of roof support,and puts forward the technical management measures of roadway roof that need to be improved.
