[0016] Figure 1 is a structural schematic view of the utility model;

[0017] In the figure: 1 - template; 11 - supporting layer; 12 - tension member; 2 - arch frame; 21 - detachable cross support; 22 - top cross support; 23 - inclined angle support; 24 - reinforcing support; 25 - pull rod; 26 - reinforcing inclined support. DETAILED DESCRIPTION

[0018] The technical scheme of the utility model will be further described below, but the scope of protection is not limited to the description.

[0019] As Figure 1 indicated.

[0020] One kind of underground mine simple and easy to dig parallel operation device of the application, it include:

[0021] The arch frame 2 of the outer side supporting template 1, the middle and lower part of the arch frame 2 is vertical plate, and the upper part is circular arc arch plate.The arch frame 2 is supported against the template 1.

[0022] The detachable cross support 21 is detachably installed on the middle and lower part of the relative inner side of the arch frame 2, and the two detachable cross supports 21 are distributed at intervals on the middle and lower part of the relative inner side of the arch frame 2 for support; the detachable cross support 21 on the lower side has a channel space.

[0023] The top cross support 22 is installed on the upper part of the relative inner side of the arch frame 2, and the top cross support 22 is fixedly connected with the inner side of the arch frame 2 through the inclined angle support 23; the inclined angle support 23 is two, and the two inclined angle supports 23 are symmetrically distributed on the upper part of the inner side of the arch frame 2.The inclined angle support 23 is fixedly connected with the arch frame 2 through the reinforcing inclined support 26.

[0024] The top cross support 22 and the inner side top of the arch frame 2 are fixedly connected through the reinforcing support 24, and the reinforcing support 24 is distributed in vertical and inclined intersection.

[0025] The template 1 is poured with the supporting layer 11 on the outer side through reinforced concrete, and the arch steel frame is embedded in the supporting layer 11; the supporting layer 11 has the tension member 12 which extends into the roadway rock stratum, and the tension member 12 is anchor rod or anchor cable.
