[0022] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.
[0023] 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.
[0024] Example 1
[0025] 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 and the 934m section west 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 primarily used to centrally clean large trackless equipment after their shift. This washing equipment produces a large amount of wastewater mixed with oil. This wastewater is discharged through the inclined slope of the car wash chamber 202 to the sewage pool in the back half of the chamber. 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 via a sewage pipe 204. This process basically achieves the goal of concentrating the large amount of sewage in the stope into the drainage chamber 205 corresponding to the 934m section.
[0026] Sewage from the drainage chambers 205 in the east and west sections of the 934m section of the 850m mid-section is discharged under its own weight through the drainage boreholes 206 between 934m and 850m into the sedimentation tank 101 in the 850m mid-section. The drainage boreholes 206 between 934m and 850m also handle the sewage treatment tasks of the 910m and 886m sections at this stage. Thus, sewage from the 934m, 910m, and 886m sections is now collected under its own weight into the sedimentation tank 101 in the 850m mid-section via the drainage boreholes 206. A water outlet is reserved on the sedimentation tank, which is connected to the drainage ditches 103 in the 850m mid-section. All sewage generated by production and daily life in the 850m mid-section also flows into the drainage ditches 103. The sewage ultimately flows through the drainage ditches 103 in the 850m mid-section and is finally collected in the central water tank 102 in the 850m mid-section.
[0027] The central water tank 102 in the middle section of 850m is designed with a supporting water pump room 105. The water pump room 105 is equipped with pumping equipment. Various water pumps in the water pump room 105 are directly connected to the central water tank 102. The water 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 water pumps in the water pump room 105 of the 1000m central water tank 102 are connected to the drainage borehole between 1000m and 1150m. Drain borehole 106 pumps sewage from the 850m and 1000m central tanks 102 to the 1150m central tank 102. Pumps in the pump house 105 at the 1150m central tank 102 then pump sewage from the 850m, 1000m, and 1150m central tanks to the surface via drainage borehole 106 at the surface-1150m section. This completes the drainage process from each section of the mine to the surface through a multi-stage relay drainage system.
[0028] Example 2
[0029] 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 the east and west according to the direction of the ore body. A drainage chamber 205 is designed in the east and west parts of the 814m section, which are respectively called the 814m east drainage chamber 205 and the 814m west drainage chamber 205.
[0030] 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 wastewater 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, and 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). The 814m section is equipped with two car wash chambers 202. Wastewater from washing the trackless equipment is drained through drainage ditches 103 in the car wash chambers 202 to a sewage pool in the back half of the chambers. A water pump is placed in the sewage pool in the back half of the chambers, connected to a drainage chamber 205 via a sewage pipe 204. This process essentially concentrates the large amount of wastewater in the stope into the drainage chamber 205 corresponding to the 814m section.
[0031] The sewage in the drainage chamber 205 in the east and west parts of the 814m section of the 700m middle section is discharged into the east and west sedimentation tanks 101 in the 700m middle section through the drainage borehole 206 from 814m to 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 700m middle section through the sewage pump, and then pumped to the central water tank 102 in the 850m middle section by the central water tank 102. At this point, all the sewage in the 700m middle section is collected in the central water tank 102 in the 850m middle section, and the lower "thin mud" is transported to the 1150m middle section 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 1150m and 1350m middle sections.
[0032] Example 3
[0033] Taking the 1000m middle section 1018m segment as an example, similar to the above-mentioned 850m middle section 934m segment and 700m middle section 814m segment, the 1000m middle section 1018m segment is divided into east and west according to the ore body trend, and a drainage chamber 205 is designed in the east and west parts of the 1018m segment.
[0034] 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 wastewater 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, and 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). The 1018m section now has four car wash chambers 202. Wastewater from washing trackless equipment is drained through the wash chambers' drainage ditches 103 to a sewage pool in the back half of the chamber. A water pump is placed in the pool, connected to a drainage chamber 205 via a sewage pipe 204. This process essentially concentrates the large amount of wastewater in the stope into the drainage chambers 205 corresponding to the 1018m section.
[0035] The sewage in the drainage chambers 205 in the east and west parts of the 1018m section of the middle section of 1000m is discharged to the water tanks in the west and east parts of the middle section of 1000m through the drainage borehole 206 of 1018m-1000m under the action of its own weight. Since the design size of the water tank in the east part of the 1018m section is larger, the water tank in the east part 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 part of the middle section of 1000m is transported to the central water tank 102 of the middle section of 1000m through the sewage pump. 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 borehole 106 of 1150m-1000m.
[0036] Finally, all kinds of sewage generated in the middle sections of 700m, 850m and 1000m underground are collected in the middle section and relayed step by step to the central water tank 102 in the middle section of 1150m. The middle section of 1150m is then pumped to the surface sedimentation tank 101 for sewage treatment.
[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
