Construction method for covering-free hole entering of mine tunnel

The invention provides a construction method for non-soil-covering tunnel entering of a mine tunnel. The construction method comprises the following steps that S1, a non-soil-covering section is subjected to underground excavation and tunnel entering; s2, monitoring and measuring; s3, designing and constructing a hole body section; and S4, designing and constructing a tunnel portal side upward slope. On the premise of ensuring the construction safety, the construction period is shortened, the engineering cost is reduced, the slope brushing amount of the mountain is reduced, and the original appearance of the mountain and the surrounding ecological environment are kept. 本发明提供一种矿山隧道无覆土进洞的施工方法，包括以下步骤：S1，无覆土段暗挖进洞；S2，监控量测；S3，洞身段设计施工；S4，洞门边仰坡设计施工。本发明可在保证施工安全的前提下，缩短施工工期、降低工程成本，并减小山体刷坡量，保持山体原貌和周边生态环境。
