Embodiment Construction

[0019] The specific embodiment of the present invention provides a mine optical fiber sensor installation method, the method is as follows figure 1 shown, including the following steps:

[0020] Step 11, drilling detection holes on the mine rock formation;

[0021] Step 12, pass the detection tube through the sealing body, and insert the sealing body equipped with the detection tube into the detection hole, the sealing body is closely matched with the detection hole, the sealing body is provided with two holes, and the two holes Used for air outlet and grouting respectively;

[0022] The detection tube in this step may include: a steel wire rope, claws and a rope-threading pipe, the steel wire rope is used to detect the variation, one end of the steel wire rope is fixed on the claw, and the other end passes through the rope-threading pipe. The rope-piercing pipe can be a common steel pipe with both ends connected. Of course, in practical situations, it is preferable to choos...

Abstract

The present invention provides a mine fiber optic sensor mounting method and special jaw which belongs to mining field. The method comprises the following procedures: perforating a detection hole on the mine terrane; passing a detection pipe through a and stuffing the sealing body provided with the detection pipe into the detection hole and guarantee the sealing body closely fit with the detection hole liquid, wherein two holes are provided on the sealing body and are used for air-out and grouting separately; sealing the air-out hole and grouting hole on the sealing body after filled the detection hole with cement mortar through grouting hole full; take out the sealing body and connecting a armored rope with a fiber optic sensor after cement mortar hardened. The method can improve certainty of measurement.

Description

technical field [0001] The invention relates to the field of mining, in particular to a method for installing a mine optical fiber sensor and a special claw. Background technique [0002] The detection of mine roof and surrounding rock is an important item for mine disaster prediction. Mine roof fall and surrounding rock collapse is one of the most serious disasters in various mines, which seriously threatens the production safety of mines and will cause huge economic losses and casualties when it occurs. In recent years, due to the continuous extension of the excavation surface and the expansion of the mining area, mine production has developed in depth, the threat of roof fall and landslide has become increasingly serious, and the task of prevention and control has become more and more difficult. Mine roof disasters seriously threaten the life safety of mine workers . Therefore, when monitoring various relevant data, not only the sensor requirements are high, but also the...
