摘要
经过多次试验研究确定的软岩煤巷锚、网、索联合支护技术,实现了软岩煤层巷道的安全生产。结果表明,该类煤层巷道的支护必须充分应用锚杆支护挤压加固、组合梁、悬吊的综合作用原理,才能达到较为理想的支护效果,及时支护和整体支护是该技术在施工中应用的关键。
According to many practices and tests of bolt, mesh and anchor combined support technogy, safe production has been achieved in soft rock mine roadway. The results indicated that integreted working principle of compression and consolidation, compound beams and cable must be fully applicated in soft rock mine roadway supporting. Due to the principle, perfect support - effect can be achieved in soft rock mine roadway supporting. It is important for the technogy that timely support and whole support is applicated in the construction.
