Embodiment Construction
[0035] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0036] like Figure 1-3 As shown, the real-time monitoring device for continuous deformation in different regions of surrounding rock of the present invention includes a stepped hollow push rod 3, a guide tube 4, a data collector 9, a surrounding rock deformation monitor 8, a probe 5, a computer 11 and several monitoring devices. The base point 2 and the probe 5 are respectively connected with the surrounding rock deformation monitor 8 and the monitoring base point 2, where the connection between the probe 5 and the monitoring base point 2 means that the probe 5 can sense and monitor the data of the monitoring base point 2, and the data collector 9 is connected with the monitoring base point 2 respectively. The surrounding rock deformation monitor 8 is connected to the computer 11. The monitoring base points 2 are respectively set in differe...

The invention relates to a different regions of surrounding rock continuous deformation real-time monitoring device and a method, and belongs to the field of mine safety, so that a defect that the monitoring device in the prior art cannot monitor different regions of surrounding rock continuous deformation in real time can be overcome. The device comprises a stepped hollow push rod which can be extended or retracted in sequence, wherein a containing cavity for containing a guide tube and a monitoring basic point is arranged in the push rod, the monitoring basic point is attached on the external of the guide tube, a probe comprises a signal transmitting and receiving device and a monitoring unit which are connected with each other, the monitoring unit is used for monitoring continuous deformation condition of the monitoring basic point part in a monitoring drill hole, the signal transmitting and receiving device is used for receiving a monitoring signal transmitted by the monitoring unit and transmitting the signal to a surrounding rock deformation monitor, and the signal transmitting and receiving device is arranged out of the guide tube and is connected with a front end of the guide tube; the surrounding rock deformation monitor comprises a real-time deformation monitoring module, and a data acquisition unit is separately connected with the surrounding rock deformation monitor and a computer. The device and the method provided by the invention are suitable for using in mining, building and tunnel construction process.
Description
technical field [0001] The invention belongs to the technical field of mine safety, and relates to a coal mine monitoring device and method, in particular to a device and method for real-time monitoring of continuous deformation in different regions in different surrounding rock layers. Background technique [0002] Coal is the main energy source of our country, and the coal mining industry is also the basis for the development of other related enterprises in the economic development of our country, and has always played an important role in our country. While the coal mine industry contributes to my country's economic development, it is also an industry with frequent production accidents, so coal mine safety issues have attracted much attention. Bolt support is usually used in mines to support the coal roadway roof, specifically, rods made of metal parts, wood parts, polymer parts or other materials are driven into the surface rock mass or the rock mass around the chamber i...
