[0013] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0014] like Figures 1 to 3 As shown, a new type of auxiliary water bunker structure in a coal mine comprises a transport tunnel 1 and a water pump room 2. The transport tunnel 1 is connected with the auxiliary water bunker 4 through the auxiliary water bunker passage 3. The water outlet of the auxiliary water bunker 4 is connected with the water pump of the water pump room 2. A winch track 5 is laid in the auxiliary water bunker passage 3 and the middle of the auxiliary water bunker. A drainage ditch 6 is arranged on one side of the auxiliary water bunker passage 3. A winch chamber 7 is arranged in the auxiliary water bunker passage 3. The top of the auxiliary water bunker 4 is connected with the ventilation connection tunnel 8 through the ventilation port 8. The auxiliary water bunker passage 3 comprises a horizontal section 9 and an inclined section 10. The inclined section 10 is connected with the auxiliary water bunker 4. The horizontal section 9 is connected with the transport tunnel 1. The winch chamber 7 is arranged in the horizontal section 9.
[0015] The utility model adopts the method of adding a secondary water tank 4 on the basis of the existing main water tank. The secondary water tank 4 adopts a new design, and the secondary water tank 4 and the secondary water tank channel 3 are formed by the anchor net cable spraying joint support structure, and the secondary water tank channel 3 is used to connect the transport tunnel 1 with the secondary water tank 4.
