Background
In the construction process of the coal mine rock tunnel TBM, the speed of tunnel support directly influences the footage speed of the TBM, and is an important factor for restricting the tunnel through time. Two main points are used for influencing the speed and the speed of roadway support, the first point is geological conditions, and the good and bad of the geological conditions relate to whether the roadway is formed stably and whether net hanging and support are easy after the TBM is tunneled. The second point is the operating space, and whether enough net hanging and supporting space exists at the first time after the TBM is tunneled or not directly determines the speed of net hanging and supporting.
Under the condition that the geological conditions are unchangeable, how to increase the suspended net and the supporting space to the maximum extent is an urgent problem to be solved. The series of TBMs with the diameters of 4-5 meters are models with a higher coal mine rock roadway, and in the series of traditional TBM equipment with the diameters, the layout of a driving motor is equally divided into 4 driven vertexes or is higher than a supporting platform, so that the space of manual operation is seriously influenced if the height of the platform is increased to protect the motor, and further the net hanging and supporting speed is influenced.
