Description
Technical field
The utility model belongs to coal mining apparatus field, is specifically related to a kind of lower protective seam mining overlying rock cranny development borehole television observation system.
Background technology
Traditional lower protective seam mining cranny development observation procedure is both-end leak stopping subsection water injection method; the method is around coal-face or work plane brattice way selects suitable observation site; such as in the district sublevel entry on work plane top, beat vertical drilling downwards; hole through the warp damage in coal seam, fissure zone and caving zone, judged the developmental state in crack by the size of water injection rate.But the method existence needs, and down-hole high pressure water, device efficiency are low, workload is large especially, water filling capsule easily scratches and can not observe the shortcoming of the developmental state in crack intuitively.In order to reduce workload, reduce costs, raise the efficiency, directly observe the developmental state in crack; the situation of method to lower protective seam mining overlying rock cranny development of down-hole upright opening borehole television observation is adopted to observe; the method selects suitable place in lower protective seam mining brattice way; play boring vertically downward to goaf, below seat earth is got in boring.Then by borehole television imaging technique, the situation of lower protective seam mining overlying rock cranny development is directly observed.But at present downward decrease speed can not more than 1.5m/s in upright opening for the probe of borehole television, and no person there will be secret note phenomenon and causes the image of observation not clear, reduce its speed in observation process.
Utility model content
The utility model exists for prior art that prior art needs that down-hole high pressure water, device efficiency are low, workload is large especially, water filling capsule easily scratches and can not observe the problems such as the shortcoming of the developmental state in crack intuitively, proposes a kind of lower protective seam mining overlying rock cranny development borehole television observation system.
The technical solution adopted in the utility model is: television system in the exploration hole of a kind of lower protective seam mining overlying strata crack; comprise underground probe, cable, tripod, pulley, depth calculator and computer; described underground probe is connected with depth calculator by cable; depth calculator is connected with computer by cable; underground probe is by cable suspension on fixed pulley, and fixed pulley is arranged on tripod top.
Described lower protective seam mining overlying rock cranny development borehole television observation system, described cable and underground probe junction are coated with vacuum silicon grease.
Described lower protective seam mining overlying rock cranny development borehole television observation system, the described fixed pulley at tripod top is connected with the main shaft of stepper motor, and the rotating speed of stepper motor is 0.8 ~ 1.5m/s.
The beneficial effects of the utility model are: 1, the utility model lower protective seam mining overlying rock cranny development borehole television observation system can improve the efficiency of observation, shorten the time of observation; Adopt the utility model lower protective seam mining overlying rock cranny development borehole television observation system to reduce workload, reduce drain on manpower and material resources, cost-saving;
2, adopt the utility model lower protective seam mining overlying rock cranny development borehole television observation system easy to carry and relatively lighter, operation is also simple, can reduce the time and manpower of carrying; Adopt the utility model lower protective seam mining overlying rock cranny development borehole television observation system can observe the height of cranny development and the development degree in crack intuitively.
