Detailed Description

Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure.

The following describes a tunneling method, a tunneling device, and an electronic apparatus for a roadway according to an embodiment of the present disclosure with reference to the drawings.

The embodiment of the present disclosure is exemplified by the tunneling method of the tunnel being configured in a tunneling device of the tunnel, and the tunneling device of the tunnel may be applied to any electronic device, so that the electronic device may implement the tunneling function of the tunnel.

As shown in fig. 1, the tunneling method of the roadway may include the steps of:

step 101, acquiring a current section profile of a roadway.

The roadway is necessary underground engineering for underground mine production, transportation, ventilation, pedestrians and the like, and the section profile of the roadway is influenced by factors such as geological conditions of the roadway, service life of the roadway, application, specifications of used transportation equipment and the like, so that the section profile of the roadway is different in shape and size.

The shapes of the section profiles of common roadways include an arch shape, a trapezoid shape and the like. The size of the profile of the section of the roadway can be determined according to factors such as transportation equipment, the maximum profile size of excavating equipment and the like.

In the disclosure, the tunneling device may determine the current section profile of the roadway by analyzing the acquired roadway section image.

And 102, determining the current central point of the roadway according to the current section profile of the roadway.

Specifically, the tunneling device performs structural analysis on the current profile of the section of the roadway after determining the profile, so that the central point of the roadway can be determined.

For example, if the current profile of the cross section of the roadway is an arch, the corresponding center point of the roadway may be the intersection point of the wide center point and the high center point of the arch.

Or, the current profile of the cross section of the roadway is trapezoidal, and the corresponding central point of the roadway can be the geometric central point of the trapezoid.

It should be noted that the above examples are only illustrative, and cannot be taken as a limitation on the center point of the cross-sectional profile of the roadway in the embodiment of the present disclosure.

And 103, determining a central free surface according to the current central point of the roadway.

The center free surface is an extension surface of any shape formed around the center.

For example, the central free surface may be a conical surface formed by performing deep cutting at a certain angle on the roadway around the central point; alternatively, the central free surface may be a circular surface formed by horizontally slitting the roadway around the central point, which is not limited in this disclosure.

In the embodiment of the disclosure, a current section profile of a roadway is obtained firstly, then a current central point of the roadway is determined according to the current section profile of the roadway, a central free surface is determined according to the current central point of the roadway, and finally a rock breaking device is adopted to enlarge the central free surface until the profile of the central free surface is the same as the current section profile of the roadway. Therefore, the method for continuously enlarging the central free surface by the stone cracking equipment is adopted to realize the tunneling of the roadway, so that the problem of low tunneling speed caused by limited use of the explosive is avoided, the potential safety hazard caused by explosion of the explosive is avoided, and the tunneling speed and the tunneling safety of the roadway are improved.
