PATENT SPECIFICATION FOR THE INVENTION ENTITLED: A NON-INTERFERENCE AUTOMATIC MONITORING INSTRUMENT FOR ROADWAY SURFACE DISPLACEMENT
The invention is described in the following statement:-
A non-interference automatic monitoring instrument for roadway surface
displacement
TECHNICAL FIELD
The present invention pertains to the technical field of instruments and meters, and relates
to the mining equipment, especially a roadway surface displacement monitor.
BACKGROUND
In recent years, as the mining depth continues to increase in the mining industry, the
pressure on the mines has become particularly obvious. Accidents such as roof fall,
roadway deformation, and rock bursts have occurred from time to time, which have
become important factors affecting the safe production of minerals. As the main
component of the mine production system, the roadway is responsible for the normal
production, transportation, ventilation and pedestrian tasks of the entire mine. Therefore,
the relative stability of the surrounding rock of the roadway during the entire life cycle is
of great significance to ensure safe and efficient production.
For this reason, it is necessary to continuously and stably monitor the deformation of the
surrounding rock of the roadway, so as to take timely measures to avoid accidents such as
layer separation and roof fall.
At present, most coal mines use manual methods to measure surface displacements.
Marks are made in advance, and the distance between two markers is measured regularly with a tape measure to provide basic data for analyzing the law of surrounding rock movement. However, there are disadvantages such as large workload, discontinuous data, and small data volume. There are also mechanical and electronic instruments, such as the
KBU1O1-200 top and bottom plate approaching dynamic alarm instrument produced by
Shandong, Yuluoka Mining Safety Engineering Co., Ltd., which extends the approaching
dynamic alarm instrument to a suitable length and then let it be supported vertically
between the top and bottom plates to be monitored. After the instrument is started, the
displacement of the top and bottom plates is monitored in real time, and the data is stored
in the instrument. However, the dynamic alarm is always supported between the roof and
the floor, which brings inconvenience to people and vehicles passing through the
roadway.
Some scholars have also proposed the use of laser ranging technology to monitor the
approach of the top and bottom plates. However, the walk of people and mine cars in the
roadway interfere with the sensors, resulting in intermittent measured data, which is not
conducive to data processing and analysis. For this reason, the present invention provides
a non-interference automatic monitoring instrument for roadway surface displacement,
which can separately monitor the amount of roadway roof subsidence and floor heave
volume, as well as the displacement of the two sides of the roadway.
SUMMARY
The technical problem to be solved by the present invention is to provide a way to
monitor the surface displacement of the roadway without interference in the roadway,
which is used to monitor the changes in the displacement of the rock strata in coal mines, metal mines, and non-metal mines, and monitor the subsidence of the roof of the roadway and the bottom heave of the floor or the displacement of the two sides of the roadway.
The technical scheme of the present invention is as follows:
An automatic monitoring instrument for roadway surface displacement without
interference includes an end sensors, wire ropes, sleeves, springs, horizontal steel pipes,
vertical steel pipes, connectors, end joints, rotating pulleys, fixing bolts, annular holes,
fixed solid rod and automatic recorder.
One end of the steel wire rope is fixed to the tail of the inner rod of the end sensor, and
the other end is fixed to the spring. Rotating pulleys with grooves are installed at the end
joints and connectors. The steel pipe is a telescopic steel pipe. The horizontal steel pipe
and the sleeve are connected by the end joint. The horizontal and vertical steel pipes are
connected by the connector. The inside of the steel pipe is evenly installed with annular
holes. The vertical steel pipe is fixed on the solid rod by fixing bolts. The automatic
recorder continuously monitors the displacement L of the measured position, that is, the
elongation of the spring, and saves it as data for collection by the collector.
Further, the automatic recorder is an LED digital display instrument and the measured
displacement is the elongation of the spring with a measurement resolution of 0.1 mm.
The end sensor is stably fixed on the surface of the road wall.
The extension range of the wire rope tail spring is 0-500mm after installation, and the
wire rope is in a straightened state after installation.
There is a groove in the middle of the rotating pulley, the width of which is slightly larger
than the diameter of the wire rope; the inner diameter of the annular hole is slightly larger
than the diameter of the wire rope, and the outer diameter is the same as the inner
diameter of the steel pipe.
The steel pipe is a telescopic arrangement, divided into inner and outer steel pipes,
connected by internal pipe threads, and can be adjusted in time according to the width
and height of the roadway.
The effects and benefits of the present invention are as follows.
(1) The roadway surface displacement non-interference monitor has a simple structure
and is convenient to use. It is used in coal mines, metal mines, and non-metal mines to
monitor the changes in the displacement of the rock strata, and monitor the amount of
roadway roof subsidence, floor bottom heave, or monitor the displacement of both sides
of the roadway.
(2) The monitor is recyclable and convenient for downhole maintenance. It can collect
data quickly and conveniently, which is convenient for continuous processing and
analysis.
(3) The monitor has a wide application range, can be easily connected to the mine
pressure monitoring system, and can effectively avoid the occurrence of safety accidents
such as layer separation and roof fall during the mine production process.
