摘要
煤巷全锚支护中的锚杆间排距必须根据围岩岩性,选择合理的理论计算方式,还要参考以往支护经验,才能最终确定出合理的锚杆间排距。文章介绍了常村煤矿采用锚杆间排距为900mm×900mm的应用;实践表明,采用较大间排距时,没有降低支护围岩强度,还节省材料费用,降低了消耗,节省了工时,提高了单进水平,确保了采掘接替,为矿井高产高效起到了重要作用。
The row line space of bolting support parameter in coal mine should be selected on the basis of surrounding rock characteristics and figured out by reasonable theory formula as ascertained through referring 900900mm in Changcun coal mine was introduced .The result shows：the bigger space parameter not only increases the intensity of support rock,but also saves material expense,reduces consumed cost,saves time,improve excavating speed and level,which plays an important role in high output and efficiency in coal mine.
