Problems solved by technology

The common disadvantage of the above-mentioned instruments is that there are few measuring points, which cannot reflect the detailed layer separation in the entire rock formation, and because the measuring ruler hangs outside the hole, it is suitable for measuring the roof, but not suitable for monitoring the bottom.
[0003] Because in coal mining, the lower layer of coal is sometimes mined first, and when the upper layer of coal is mined, the coal seam floor will also be separated. For production safety, it is necessary to monitor the separation of the bottom floor. So far, there is no monitoring of the coal seam floor. monitor

Embodiment Construction

[0023] Referring to the accompanying drawings, the technical solutions of the embodiments of the present invention will be further described by taking four measuring points as examples.

[0024] Such as figure 1 with figure 2 As shown, the monitoring instrument of the embodiment of the present invention is mainly composed of a base point anchor head 1 , a stay rope 2 , a base casing 3 and a measuring ruler 6 . Connect four horizontal extension tubes 4 on the top of the base casing 3, each extension tube 4 is provided with an upward observation slot 5, and a measuring ruler 6 is installed in the extension tube 4, and the measuring ruler 6 The maximum measuring range is 150mm; there are 15 large grids, and each large grid is 10mm; each large grid is divided into 5 small grids, and each small grid is 2mm. Can see measuring ruler 6 readings from observation seam 5, and each measuring ruler 6 is all connected respective anchor head 1 by stay rope 2, and each stay rope 2 is movab...

Abstract

The invention discloses a multi-position base plate delaminating monitor and a using method thereof. A plurality of extending pipes in the horizontal direction are mainly connected to the top of a base body sleeve of the traditional monitor; each extending pipe is provided with an upward observing seam; a measuring ruler is installed in each extending pipe, and the indication of the measuring rulers can be viewed from the observing seams; each measuring ruler is connected with respective anchor head by a pull rope; and each pull rope is movably connected to each measuring ruler by a screw, and the pull ropes respectively have different lengths in a drilling hole. When the multi-position base plate delaminating monitor is used, the delaminating condition of a base plate stratum is judged according to the displacement change of two upper and lower adjacent measuring points. The invention provides base plate delaminating data for the safety production of a coal mine, is convenient for a staff to adopt a safety measure in time, and prevents accident generation.

Description

technical field [0001] The invention relates to a coal mine monitoring instrument. Background technique [0002] At present, the monitoring of the separation layer of the surrounding rock in the mine roadway or working face is mainly to monitor the roof of the roadway, and the number of monitoring points for the separation layer is relatively small, generally 1-2. Such as the roof subsidence and separation layer indicator (application number 98243841), the surrounding rock separation layer monitoring instrument (application number 200730013939), the surrounding rock separation layer monitoring and alarm instrument (application number 200420039443), and the multi-directional surrounding rock separation layer monitoring disclosed in the Chinese patent Alarm instrument (application number 200620083761) and multi-directional dual-function surrounding rock separation layer monitoring and alarm instrument (application number 200710013233), etc. The structures of all these instrum...
