[0015] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.
[0016] The distance between each middle section 1 in the mine is 150m, and the distance between each subsection 2 on the middle section is 24m.
[0017] Embodiment 1, Taking the 934m section in the middle section of 850m as an example, the 934m section is divided into two parts, east and west, according to the direction of the ore body, hereinafter referred to as the 934m section east part and the 934m section west part respectively. The east and west parts of the 934m section are each designed with a drainage chamber 205, and each production panel 201 of the 934m section is designed with a panel small water tank 203. The panel small water tank 203 in the production panel 201 is mainly used to store fissure water and wastewater generated during the drilling process of the drilling rig. The sewage is transported to the nearest drainage chamber 205 through the sewage pipe 204 through the water pump in the panel small water tank 203 of the production panel 201. The general design specifications of the drainage chamber 205 are: 30m×4.6m×4.3m (length×width×height). The 934m section is equipped with three car wash chambers 202, which are mainly used to centrally wash large trackless equipment that have completed the work on duty. The washing equipment will produce a large amount of sewage mixed with oil. The sewage generated by the washing equipment is discharged to the sewage pool in the back half of the chamber through the inclined slope of the car wash chamber 202. A water pump is placed in the sewage pool in the back half of the chamber, and the water pump is connected to the drainage chamber 205 through the sewage pipe 204. This process basically realizes the concentration of a large amount of sewage in the mining field to the drainage chamber 205 corresponding to the 934m section.
[0018] The sewage in the drainage chamber 205 in the east and west of the 934m section of the middle section of 850m is discharged to the sedimentation tank 101 in the middle section of 850m through the drainage borehole 206 of 934m-850m under the action of its own weight. The drainage borehole 206 of 934m-850m also undertakes the sewage treatment task of the 910m section and the 886m section at this stage. So far, the sewage of the 934m section, the 910m section and the 886m section are all collected to the sedimentation tank 101 in the middle section of 850m by the drainage borehole 206 under the action of their own weight. There is a water outlet reserved on the sedimentation, which is connected to the drainage ditches 103 in the middle section of 850m. The sewage generated by production and life in the middle section of 850m also enters the drainage ditch 103. The sewage is finally collected in the central water tank 102 in the middle section of 850m through the drainage ditch 103 in the middle section of 850m.
[0019] The central water tank 102 in the middle section of 850m is designed with a matching pump house 105. The pump house 105 has pumping equipment. Various water pumps in the pump house 105 are directly connected to the central water tank 102. The pumps directly pump the sewage in the 850m water tank to the central water tank 102 in the middle section of 1000m through the drainage borehole 106 between 850m and 1000m. The pumps in the pump house 105 in the 1000m central water tank 102 use the drainage borehole 106 between 1000m and 1150m to pump the sewage to the central water tank 102. The water borehole 106 pumps the sewage from the central water tank 102 at the middle section of 850m and 1000m to the central water tank 102 at the middle section of 1150m. The pump in the water pump room 105 at the central water tank 102 at the middle section of 1150m pumps the sewage from the central water tank 102 at the middle section of 850m, 1000m and 1150m to the surface through the drainage borehole 106 at the middle section of 1150m. So far, the sewage from each middle section of the well has been discharged from the well to the surface through the multi-stage relay drainage system.
[0020] Embodiment 2, Taking the 814m section in the middle section of 700m as an example, similar to the 934m section in the middle section of 850m mentioned above, the 814m section in the middle section of 700m is divided into east and west according to the direction of the ore body, and a drainage chamber 205 is designed in the east and west of the 814m section, which are respectively called the 814m east drainage chamber 205 and the 814m west drainage chamber 205.
[0021] A small water tank 203 is designed in each production panel 201 of the 814m section. The small water tank 203 in the production panel 201 is mainly used to store fissure water and waste water generated during the drilling process of the drilling rig. A water pump is placed in the small water tank 203 of the production panel 201. The water pump is connected to the sewage pipe 204. The sewage pipe 204 runs from the mining field through the layered connecting road and the segmented road to the drainage chamber 205 in the east and west of the 814m section. The general design specifications of the drainage chamber 205 are: 30m×4.6m×4.3m (length×width×height). The 814m section is equipped with two car wash chambers 202. The sewage generated by washing the trackless equipment is discharged to the sewage pool in the rear part of the chamber through the drainage ditch 103 of the car wash chamber 202. A water pump is placed in the sewage pool in the rear part of the chamber, and the water pump is connected to the drainage chamber 205 through the sewage pipe 204. This process basically realizes the concentration of a large amount of sewage in the mining field to the drainage chamber 205 corresponding to the 814m section.
[0022] The sewage in the drainage chamber 205 in the east and west of the 814m section of the middle section of 700m is discharged to the east and west sedimentation tank 101 in the middle section of 700m through the drainage borehole 206 of 814m-700m under the action of its own weight. The sewage in the sedimentation tank 101 settles under the action of its own weight to form upper "clear liquid" and lower "thin mud". The upper "clear liquid" is discharged into the central water tank 102 in the middle section of 700m through the sewage pump, and then pumped to the central water tank 102 in the middle section of 850m by the central water tank 102. At this point, all the sewage in the middle section of 700m is collected in the central water tank 102 in the middle section of 850m, and the lower "thin mud" is transported to the middle section of 1150m through the 700m horizontal vacuum pump. The "thin mud" is then relayed to the surface for treatment in the form of "water carrying mud" through the vacuum pumps in the middle sections of 1150m and 1350m.
[0023] Embodiment 3, Taking the 1018m section in the middle section of 1000m as an example, similar to the 934m section in the middle section of 850m and the 814m section in the middle section of 700m, the 1018m section in the middle section of 1000m is divided into the east and west according to the direction of the ore body, and a drainage chamber 205 is designed in the east and west of the 1018m section.
[0024] A small water tank 203 is designed in each production panel 201 of the 1018m section. The small water tank 203 in the production panel 201 is mainly used to store fissure water and waste water generated during the drilling process of the drilling rig. A water pump is placed in the small water tank 203 of the production panel 201. The water pump is connected to the sewage pipe 204. The sewage pipe 204 runs from the mining area through the layered connecting road and the segmented road to the drainage chamber 205 in the east and west of the 814m section. The general design specifications of the drainage chamber 205 are: 30m×4.6m×4.3m (length×width×height). There are 4 car wash chambers 202 in the 1018m section. The sewage generated by washing the trackless equipment is discharged to the sewage pool in the rear part of the chamber through the drainage ditch 103 of the car wash chamber 202. A water pump is placed in the sewage pool in the rear part of the chamber, and the water pump is connected to the drainage chamber 205 through the sewage pipe 204. This process basically realizes the concentration of a large amount of sewage in the mining field to the drainage chamber 205 corresponding to the 1018m section.
[0025] The sewage in the drainage chambers 205 in the east and west of the 1018m section of the middle section of 1000m is discharged to the water tanks in the west and east of the middle section of 1000m through the drainage boreholes 206 of 1018m-1000m under the action of its own weight. Since the designed size of the water tank in the east of the 1018m section is larger, the water tank in the east of 1000m is also used as the central water tank 102 of the middle section of 1000m. The sewage in the water tank in the west of the middle section of 1000m is transported to the central water tank 102 of the middle section of 1000m through a sewage pump, and the sewage in the middle section of 1000m is then pumped to the central water tank 102 of the middle section of 1150m through the drainage boreholes 106 of 1150m-1000m.
[0026] Finally, all kinds of sewage generated in the middle sections of 700m, 850m and 1000m underground are collected in the central water tank 102 in the middle section of 1150m through the middle section collection and step-by-step relay method, and then pumped to the surface sedimentation tank 101 for sewage treatment.
[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
