Description
Technical field
The present invention relates to technical field of coal mine, and in particular to one kind is suitable for detection high seam top plate above rock, tunnel
Roof delamination, drilling quality, hydrofracturing effect wireless inspection instrument for borehole device and method.
Background technique
When coal mine carries out coal column drilling, the work such as hydrofracturing, need into quasi- detection roadway surrounding rock and roof
Strata structure, including rock stratum attribute, rock stratum performance level and cranny development situation, to be provided for roadway support and hydrofracturing
Foundation.
Wired inspection instrument for borehole is widely used to geological conditions assessment when coal production, roadway support design, mainly
For detecting top plate and above rock geological structure, roadway roof absciss layer, drilling quality, hydrofracturing effect etc., especially to brill
The detection of hole quality, hydrofracturing effect and face roof rock structure can intuitively, clearly be shown by display
Show.By recording digital code instrument, deposits and analyzed in a computer for technical staff, make objective judgement and decision in time, it both can be as far as possible
The generation for avoiding accident, support form and parameter foundation but also as tunnel reduce unnecessary investment, video recording, image money
Material can be reserved for and do permanent record.It is a kind of reliable side for detecting top plate and above rock geological conditions using inspection instrument for borehole
Method.
The technology maturation of current wired inspection instrument for borehole device, the producer of production, model are also relatively more, but basic structure is general
