摘　　要：凤凰山煤矿在掘进煤巷时,采用传统的支护方式,造成巷道掘进成本居高不下。通过现场调查统计和分析,找出了影响巷道掘进支护成本高的主要原因是金属支架结构不合理和掘进工艺落后。在保证安全生产的前提下,经过合理改进掘进支护金属支架参数和支护工艺,大大地降低了掘进成本,提高了单进度,取得了明显的支护效果和较好的经济、社会效益。The use oftraditionalsupport pattern in coal roadway driving once caused high driving cost ofcoal roadways in Fenghuangshan Coal Mine.He on-the-spot investigation,statistics and analysis show that the cause affecting high support cost in roadway driving is the unreasonable structure of metal support and back-ward driving technology.Under prerequisite of guaranteeing safety production,the reasonable improvement of metal support parameters and support technology has greatly reduce driving cost,raised unit progress and obtained marked support effect and better economic and social benefits.
