Description
Technical field
The present invention relates to field of mining, relate in particular to a kind of mine fiber optic sensor mounting method and special jaw.
Background technology
The detection of mine roof and country rock is the big event of mine disaster prediction, and it is one of especially big disaster of all kinds of mines that mine roof fall country rock caves in, and the production safety in mine in serious threat, can cause enormous economic loss and casualties during generation.In recent years, because the not section of development end is extended and the expansion of limit of mining, mine production develops in depth, and roof fall, the threat of landslide are also serious day by day, and the task of preventing and treating is also more and more arduous, and mine miner's life security in the serious threat of mine roof disaster.So not only the requirement of sensor is high but also installation is also quite reliable when the various related data of monitoring.
The mine fiber optic sensor mounting method that prior art provides is, uses piling to hang, and setscrew is fixed, and resin medicine rod is perhaps directly with hard thing plug reality.
In realizing process of the present invention, the inventor finds prior art, and there are the following problems:
Measure error is big
Because the scheme of prior art can produce very big gap when mounted and be connected not closely with on every side detected object, so can produce very big measure error.
Summary of the invention
In view of above-mentioned existing in prior technology problem, the specific embodiment of the present invention provides a kind of mine fiber optic sensor mounting method and special jaw, and this method has the advantage that improves certainty of measurement.
The specific embodiment of the invention provides a kind of mine fiber optic sensor mounting method, and this method comprises:
A, on the rock stratum, mine, beat and detect the hole;
B, detector tube is passed seal, and the described seal that detector tube will be housed fills in described detection hole, and guarantee that described seal tightly cooperates with described detection hole, described seal is provided with two holes, and it is respectively applied for gives vent to anger and slip casting;
Described detector tube comprises: wire rope, claw and wire rope handling pipe, and described wire rope one end is fixed on the described claw, and the other end passes described wire rope handling pipe;
C, cement mortar filled with described detection hole by injected hole after, venthole and injected hole on the airtight described seal;
D, treat cement mortar sclerosis after, take out described seal and described wire rope be connected with Fibre Optical Sensor.
The specific embodiment of the invention also provides a kind of special jaw of said method, described claw comprises: column type body, at least two juts and hook, described jut is fixed on the cylinder of described column type body, described hook is fixed on the soffit of column type body, and the external diameter of described column type body is less than the internal diameter of the described wire rope handling pipe of said method.
The technical scheme that is provided by the specific embodiment of the invention described above as can be seen, the described technical scheme of specific embodiments of the invention makes detector tube and rock stratum, mine combine closely by the method for slip casting, thereby reduced the gap that produces when installing, and then avoided owing to being connected the excessive problem of detection error that does not closely cause with on every side detected object, thereby has the advantage that improves certainty of measurement.
Description of drawings
Fig. 1 provides a kind of flow chart of mine fiber optic sensor mounting method for the specific embodiment of the invention.
The front view of the special jaw of the method for claim 1 that Fig. 2 provides for the specific embodiment of the invention.
The right view of the special jaw of the method for claim 1 that Fig. 3 provides for the specific embodiment of the invention.
The specific embodiment
The specific embodiment of the invention provides a kind of mine fiber optic sensor mounting method, and this method comprises the steps: as shown in Figure 1
Step 11, on the rock stratum, mine, beat and detect the hole;
Step 12, detector tube is passed seal, and the seal that detector tube will be housed fills in this detection hole, the sealing body tightly cooperates with this detection hole, and the sealing body is provided with two holes, and these two holes are respectively applied for gives vent to anger and slip casting;
Detector tube in this step can comprise: wire rope, claw and wire rope handling pipe, and this wire rope is used for the change detected amount, and this wire rope one end is fixed on this claw, and the other end passes the wire rope handling pipe.This wire rope handling pipe can certainly in actual conditions, preferably be selected stainless steel pipe for the steel pipe of common two ends conducting.
Optionally, this wire rope is the stainless steel wire rope.
Step 13, cement mortar filled with this detection hole by injected hole after, venthole and injected hole on the airtight sealing body;
Step 14, treat cement mortar sclerosis after, take out the sealing body and this wire rope be connected with Fibre Optical Sensor.
Above-mentioned seal can be stopper or foam plug, wherein, preferentially selects foam plug, be difficult for taking out because can expand after stopper is met water, and foam plug is difficult for expanding after meeting water, so the sealing body uses foam plug, more convenient taking-up.
Optionally, the cement mortar in the above-mentioned steps 13 can be, the mixture of cement, yellow sand and water, and the mass ratio of this mixture can be, cement: yellow sand: water=4: 1: 25, the wherein above yellow sand of preferred 80 orders of yellow sand or 80 orders.After the ratio of cement mortar cooperated according to the above ratio, particularly select the above yellow sand of 80 orders or 80 orders, can make cement mortar infilter the slit of rock stratum, mine, it is tightr to make that detector tube combine with the rock stratum, mine, further the precision of raising detection.
The method that the specific embodiment of the invention provides, detect the hole by on the rock stratum, mine, beating, installation and measuring pipe in detecting the hole, and fill up fixing clearance between detector tube and the rock stratum, mine by grouting mode, make detector tube and rock stratum, mine combine closely, reduced the gap that produces when installing, and then avoided having the advantage of raising certainty of measurement owing to is connected the tight detection error excessive problem that causes with on every side detected object.
The specific embodiment of the invention also provides a kind of special jaw of said method, the structure of this claw is shown in Fig. 2,3, comprise, column type body 21, at least two juts 22 and link up with 23, this jut 22 is fixed on the cylinder of column type body 21, this hook 23 is fixed on the soffit of column type body 21, and the external diameter of this column type body is less than the internal diameter of the described wire rope handling pipe of said method.
