| 摘 要： | 综放面的底煤巷由于顶帮压力大,难于支护,巷道维护工作量大,采用传统的棚式支护无法满足安全、生产要求,而锚杆支护以其主动支护、及时支护、支护阻力大的特点,在煤巷中得到了广泛的推广和应用。尤其是在顶帮压力较大的巷道中,锚杆支护的优越性得到了充分的体现,保证了巷道支护的稳定性和回采的快速推进。

| Abstract: | Because top slope pressure in floor roadway of workface,supporting is difficalt,maintenance of roadway have large working load,saft and product can′t be satisfied with traditional beam support,bolt support are spreaded and applicated in roadway because of active ,time supporting and supporting resistance.Bolt support gives good expression to top slope pressure roadway,it guarantees stability of supporting and driving speed of coal winning. |
