FIELD OF THE INVENTION
[0001] The present invention relates to the technical field of mining machinery, and in particular, to an excavating, supporting and anchoring integrated machine system for downhole rapid excavating and a use method thereof.
DESCRIPTION OF RELATED ART
[0002] As the mining depth of a production mine is increasing, a ground stress and a surrounding rock stress and deformation are complex and diverse. An anchor net support is used by a majority of tunnel mining because of a good supporting effect, a wide range of application, flexibility in adapting to changes according to tunnel conditions, and other features of the anchor net support. However, in a current process of tunnel excavation, a mechanized excavation efficiency is very high, and a tunnel support speed lags far behind an excavation speed. Due to a serious mismatch of the excavating time, supporting time and anchoring time, a footage time of an excavating machine is far less than a total working time, and in a large amount of time, the excavating machine stops operating for performing a support operation.
One direction to resolve the serious mismatch of the excavating time, supporting time and anchoring time is to implement an excavating, supporting and anchoring parallel operation.
One direction to resolve the serious mismatch of the excavating time, supporting time and anchoring time is to implement an excavating, supporting and anchoring parallel operation.
[0003] A patent entitled "UNMANNED TUNNEL EXCAVATING AND ANCHORING
INTEGRATED MACHINE" is disclosed in CN104500086A. A support system thereof only involves temporary support and anchor rod support, and cannot resolve a problem of falling of small pieces of surrounding rock. If an anchor net needs to be installed, a working section needs to be manually approached, and a cutting head needs to be stopped for safety of workers.
Therefore, the excavating, supporting and anchoring parallel operation cannot be implemented, and dust, noises and other factors also greatly threaten the safety of the workers. A cutting part thereof can perform cutting by only one feed each time the cutting part stops to operate, and the efficiency is relatively low.
