Abstract

The invention discloses a roadway tunneling method. The method comprises the steps that a tunneling unit is controlled to conduct tunneling operation, and a temporary supporting device is controlled to conduct temporary supporting operation; when the temporary supporting distance reaches a preset distance threshold value, the tunneling unit is controlled to stop tunneling operation; and after ventilation and dust fall are conducted on the shutdown working face of the tunneling unit and safety is determined, a roadway is subjected to long-time supporting operation. According to the roadway tunneling method, tunneling operation and supporting operation are separated in space and time, time-sharing and segmented roadway tunneling is achieved, workers are prevented from working in an extremelysevere environment, the risk that related employees suffer from occupational diseases is reduced, and the number of dead people caused by the occupational diseases is reduced.

Description

technical field [0001] The present application relates to the technical field of mining, in particular to a roadway excavation method. Background technique [0002] In related technologies, the mechanized excavation of mine roadways generally adopts the excavation method of excavation and support. The working face of the roadway requires a large number of workers to work together at the same time. Occurrence of various occupational diseases, such as pneumoconiosis, deafness, skin diseases, rheumatism, nervous system diseases, etc. The number of deaths due to occupational diseases has far exceeded the number of accident deaths every year. Contents of the invention [0003] This application aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, this application proposes a roadway excavation method to ensure the health of staff, reduce the risk of staff suffering from occupational diseases, and reduce the numbe...
