Abstract

The invention relates to a multisection continuous observing method for feeding back a tunnel surrounding rock deforming rule, which is suitable for support engineering of a mine tunnel. The tunnel length range of a tunneling influence period is judged according to the surrounding rock condition and the tunneling speed of the tunnel; 5 to 10 observing stations are distributed and installed in a range not smaller than the length at an observing station interval which is integral multiple of daily tunneling size of the tunnel; the observation is carried out once a day after installation and keeps for 3-5days, and the data for reflecting the tunnel deforming rule can be obtained. By the system distribution of the observing stations and the improvement of the observing method, the invention reduces the observing period from 50-80 days to 3-5 days, greatly reduces the workload of observing staffs and has high feedback speed and less influence on the tunneling construction of the tunnel; the reflected mine pressure rule can provide reliable information in time for guiding site construction and provide important basic data for solving the problem of support of the deep soft rock tunnel.

Description

technical field

[0001] The invention relates to a continuous observation method, in particular to a multi-section continuous observation method for feeding back the deformation law of the surrounding rock of the roadway supporting engineering. Background technique

[0002] As a channel for safe production in coal mines, the importance of mine pressure observation in roadways is self-evident. On the one hand, the reasonable control and maintenance of the roadway is related to the normal production of the mine and the life safety of the miners, and the accidents in the roadway are highly accidental and destructive, so daily mine pressure observations must be carried out to reflect the maintenance status of the surrounding rock. Take measures in time when abnormal situations occur; on the other hand, with the increase of coal mine mining depth, the control problems of deep and weak and broken surrounding rock roadways become more and more obvious, and the support technology nee...
