Description
Technical Field
The utility model relates to a colliery technical field, concretely relates to "bore and push away" integrative accurate drilling peep at device suitable for survey broken country rock deformation and crack expansion condition.
Background
When the coal mine works for coal pillar drilling, hydraulic fracturing and the like, the rock stratum structures of surrounding rocks of the roadway and a coal seam roof, including rock stratum attributes, rock stratum integrity and fracture development conditions, need to be accurately detected, so that a basis is provided for roadway support and hydraulic fracturing. The drilling is peered and is used for detecting coal seam structure, tunnel roof abscission layer (breakage), drilling quality, tunnel grout effect, especially observes at the tunnel roof abscission layer that the anchor net was strutted, and the observation of working face roof rock stratum structure all can be through the direct-viewing, clear demonstration of display and come out. Through the digital recorder, the data are stored in a computer for workers to analyze, and objective judgment and decision are made in time. The method can avoid accidents as much as possible, and can be used as a basis for determining roadway support forms and parameters, thereby reducing unnecessary investment. Therefore, the adoption of the drilling peering instrument is a reliable method for detecting the geological conditions of the top plate and the overlying surrounding rock, and has important significance for controlling the stability of the surrounding rock.
At present, the technology of a drilling peeping instrument is mature, and manufacturers and models of the drilling peeping instrument are more, but the basic structure generally comprises a photoelectric probe, a push rod, a fixing device, an explosion-proof box, a display, a video recorder, a cable and the like. The diameter of a photoelectric probe of a drilling peeping instrument commonly used for coal mines is generally phi 22mm, the diameter of a drilling hole is phi 28mm, the diameter of a push rod is phi 20mm, the push rod is made of a metal stainless steel pipe generally, and the length of each section of the steel pipe is 1 m. The drilling depth is generally 10-20m, the diameter of the cable is phi 5mm, a power line of a photoelectric probe and a data line for transmitting signals to a host are arranged in the cable, and a built-in battery can work for 6 hours.
The basic procedure for observing the top plate in the domestic coal mine is that firstly, 10-20m drill holes are drilled upwards from the top plate by using an anchor cable drilling machine, the diameter of each drill hole is phi 28mm, then the drill holes are washed clean by using water, a drill hole observing instrument is started, a photoelectric probe connected with a cable is sent into each drill hole by using a push rod, video or pictures are recorded in the conveying process, rock stratum information at different depths is recorded, and the later-stage processing analysis is carried out.
However, in many cases, especially in high stress weak roadways, the roof condition is poor, which easily causes deformation and collapse of the drill hole, and during the process of the drill hole peeping instrument entering the hole channel, the probe of the drill hole peeping instrument is easily blocked in the collapsed and deformed drill hole, which causes a great amount of economic loss. Simultaneously when using the device to peep the drilling deep, peep the personnel and need waste a large amount of time at the installation of propelling movement pole and dismantle the in-process. Firstly, because its propelling movement pole festival is more, carry and connect the pole in-process and wasted a large amount of manpowers and time, seriously influence the efficiency of peeping the experiment. Secondly, when peeping the deep hole, the push rod of connection is more, and if the meshing between the push rod is not fastened, can make the bulk rigidity reduction of push rod, and then increased the degree of difficulty of propelling movement probe in toward drilling. Thirdly, because will install probe and video cable (video cable is connected with the degree of depth encoder) in the one end of push rod, so can be along with the increase of peeping the degree of depth, video cable avoids having the off tracking phenomenon to appear and causes the great error of range finding to appear, causes inaccurately when the figure is peeped in the record.
