摘要
针对宜兴煤业采掘接替紧张的问题,提出了巷道锚杆(索)分次支护的技术措施。在保证巷道围岩基本稳定的前提下,优先进行巷道掘进,在与掘进工作面间隔一定距离,不影响巷道掘进施工环节时,再进行支护作业环节,从而提高巷道掘进速度。经过现场试验,分次支护巷道掘进速率提升了28.1%。
Aiming at the shortage of mining replacement in Yixing Coal Industry,the technical measure of roadway bolt(cable)step-by-step support is put forward.Under the premise of ensuring the basic stability of the surrounding rock of the roadway,priority should be given to roadway driving,and support operation should be carried out when there is a certain distance between the roadway and the heading face,which does not affect the roadway excavation construction link,so as to improve the roadway driving speed.Through the field test,the driving rate of the roadway with step-by-step support has been increased by 28.1%.
