Description
Technical field
The present invention relates to the coal rock layer thickness measures of mining Technology Underground Coal Mine more particularly to a kind of coal mine fully-mechanized mining working
Tool and measurement method.
Background technology
Down-hole combined mining working measures mining thickness at present, and generally use hangs ruler method, i.e., by measuring working face top
Then beam adds hydraulic support top beam height and bracket base obtains the face of adopting at a distance from bottom plate to the distance of hydraulic support foundation
Mining thickness or coal seam thickness, but this method has the following disadvantages and insufficient in actual application：
（1）It needs to measure below engineers and technicians or coal pillar robbing group inspector to coal wall using this method, and needs
Work can be measured when fully-mechanized mining working shuts down production, it is bad encountering coal seam conditions（Easy slice caving, roof fall）When, personnel
It is that can not stand to measure in coal wall side, it is big measures difficulty.
（2）It is that cannot accurately measure coal seam using this method when working face coal seam thickness changes or do not plan a successor
Or rock thickness.
（3）The tape measure that suspension ruler method uses at present is not easy to be suspended on above hydraulic support front-axle beam, even if can if in suspension
There is deviation in final measurement data caused by the position difference of different personnel suspension.
It is, therefore, desirable to provide the coal rock layer tool for measuring thickness and measurement method of a kind of New Coal Mine fully-mechanized mining working, with
Meets the needs of mining Technology Underground Coal Mine development.
Invention content
Present invention solves the technical problem that：There is provided a kind of New Coal Mine fully-mechanized mining working coal rock layer tool for measuring thickness and
Measurement method, existing measurement difficulty is big when measuring mining thickness to traditional suspension ruler method, measures inaccurate and number
According to the big problem of error.
Technical scheme of the present invention：
A kind of coal rock layer tool for measuring thickness of coal mine fully-mechanized mining working, including shrinkage-rule, fixed rotary shaft and two are scalable
Foot is measured, described two scalable measurement foot one end are hinged by fixed rotary shaft, and the shrinkage-rule box body end setting exists
On the scalable measurement foot of any bar, the shrinkage-rule hook end is fixedly connected with another scalable measurement foot.
It is provided with scale on the scalable measurement foot.
A kind of coal rock layer tool for measuring thickness of coal mine fully-mechanized mining working, measurement method include the following steps：
Step 1：Two scalable measurement feet are extended to working face wall by survey crew station below hydraulic support shielding；
Step 2：Two scalable measurement feet are opened, two scalable measurement sole ends is made to be stretched respectively to coal rock layer top to be surveyed
Portion and bottom；
Step 3：Read shrinkage-rule on data, according to the height of similar triangles than equal to bottom edge than principle, you can calculate
Obtain the working face mining height that need to be measured or coal petrography layer thickness.
Beneficial effects of the present invention：Coal rock layer tool for measuring thickness and the measurement of a kind of New Coal Mine fully-mechanized mining working are provided
Method has the following advantages compared with prior art：
（1）Measurement to coal petrography thickness can be realized without station in survey crew below coal wall, though face roof condition compared with
Difference, survey tool using the present invention can also measure, and measurement result is accurate and safe operation.
（2）Measurement work can be realized on working surface hydraulic support top beam without hanging, by reading on shrinkage-rule
Data, according to the height of similar triangles than equal to bottom edge than principle, you can be calculated the working face mining height that need to be measured or
Coal petrography layer thickness, will not because between working surface hydraulic support and coal wall drop and inclination angle due to influence coal（Rock）Layer thickness measures.
（3）It is of less demanding to survey crew, i.e., it will not cause large error because different personnel measure.
Description of the drawings
Fig. 1 is survey tool structural schematic diagram of the present invention；
Fig. 2 is to measure schematic diagram using survey tool of the present invention；
It is identified in figure：1, shrinkage-rule, 2, scalable measurement foot, 3, fixed rotary shaft, 4, coal seam, 5, hydraulic support.
Specific implementation mode
The present invention is described further below in conjunction with the accompanying drawings, a kind of coal petrography of coal mine fully-mechanized mining working of the present invention
Layer thickness survey tool, including shrinkage-rule 1, fixed rotary shaft 3 and two scalable measurement feet 2, described two scalable surveys
2 one end of foot-measuring is hinged by fixed rotary shaft 3, two scalable measurements feet 2 can be opened up by fixation rotary shaft 3 it is open and close,
On scalable the measurements foot of any bar 2, the 1 hook end of shrinkage-rule and another can for described 1 box body end of the shrinkage-rule setting
The flexible foot 2 that measures is fixedly connected.
It is provided with scale on the scalable measurement foot 2, can be used for calculating by the scale read on scalable foot 2
The thickness of coal rock layer.
A kind of coal rock layer tool for measuring thickness of coal mine fully-mechanized mining working, measurement method include the following steps：
Step 1：Two scalable measurement feet 2 are extended to working face wall by survey crew station below the shielding of hydraulic support 5；
Step 2：Two scalable measurement feet 2 are opened, two scalable 2 bottom ends of measurement foot is made to be stretched respectively to need to extremely survey coal rock layer
Top and bottom；
Step 3：Read shrinkage-rule 1 on data, according to the height of similar triangles than equal to bottom edge than principle, you can calculate
Obtain the working face mining height that need to be measured or coal petrography layer thickness.
Embodiment 1：It measures as shown in Figure 2 and adopts face coal seam height, shrinkage-rule 1 is installed on scalable measurement foot 2 first,
Scalable measurement 2 bottom end of foot is set to be up to the four of 3 vertical range of fixed rotary shaft for shrinkage-rule 1 to the vertical range of fixed rotary shaft 3
Times, as shown in Fig. 2, the vertical range of scalable measurement 2 bottom end of foot to fixed rotary shaft 3 is arranged to 4D, shrinkage-rule 1 is arrived
Fixed 3 vertical range of rotary shaft is arranged to D, and two scalable measurement feet 2 are then unfolded, make two scalable 2 bottom ends of measurement foot
It is stretched respectively to need to extremely survey at the top and bottom of coal rock layer, the reading L on shrinkage-rule 1 is read, according to the height of similar triangles ratio etc.
In bottom edge than principle, proportion of utilization relationship is multiplied by corresponding proportion, therefore it is 4L to calculate coal seam height.
