As shown in fig. 1 and 2, the phosphorite roof anchor cable eye construction device comprises an air-leg rock drill 1, wherein the air-leg rock drill 1 is connected with a drill rod 2, the drill rod 2 is connected with a drill bit 3, a spraying device 4 is arranged on the air-leg rock drill 1, the spraying device 4 is in sliding connection with the drill rod 2, the spraying device 4 is connected with a water tank 6 through a water pipe 5, and a water pump 7 is arranged on the water pipe 5. The gas-leg rock drill 1 is connected to a drill rod 2 by a connecting rod 10. The arrangement solves the problem that the length of the drill rod is not enough, and is convenient for drilling an anchor cable eye which meets the requirement (5 m).

Preferably, the spraying device 4 comprises a sliding ring 4.1 which is sleeved outside the drill rod 2 in a sliding manner, the sliding ring 4.1 is connected with a spraying ring 4.3 through a plurality of connecting pipelines 4.2, the spraying ring 4.3 are communicated with the inner cavity of the water pipe 5, and spraying heads are arranged on the upper sides of the connecting pipelines 4.2 and the spraying ring 4.3. The arrangement enables the sprayed water mist to form a circle of water curtain, the water curtain is arranged around the drill hole, dust sprayed out of the drill hole is surrounded by the water curtain, and the dust is combined with water drops when flying out, so that the dust falling effect is achieved.

Preferably, the plurality of connecting pipes 4.2 are uniformly arranged in a radial shape, and the spray headers on the connecting pipes 4.2 are more dense as the distance from the sliding ring 4.1 is farther. Such an arrangement makes the sprayed water curtain more uniform.

Preferably, the spray heads on the spray ring 4.3 are fan-shaped spray heads, and when the fan-shaped spray heads spray, the fan-shaped water curtain is enclosed into a cylindrical water curtain to enclose the drilling hole, so that a relatively complete cylindrical water curtain can be enclosed.

Preferably, a filter screen 8 is arranged between the sliding ring 4.1 and the spraying ring 4.3, and the filter screen 8 can not only block dust and prevent the dust from entering the rock drill, but also prevent the dust rushed out at high speed from directly rebounding, absorb a part of kinetic energy and filter a part of dust.

Preferably, a fixing seat 9 is connected to the lower side of the spray ring 4.3, and the spray device 4 is fixed on the air-leg rock drill 1 through the fixing seat 9. The fixing base 9 in this embodiment is welded to the airleg rock drill 1, so that the structure is more stable.

The working principle of the embodiment is as follows: all the drill rods 2 used in the embodiment are 25mm square drill rods.

In use, the device is first placed in position. Drilling is carried out according to the following steps:

1. the TY29 type airleg rock drill 1 is matched with a 1.6m drill rod 2 and a 40mm drill bit 3 and is vertically driven into a top plate by 1.5 m;

2. changing a drill rod 2 with the diameter of 1.6m into a drill rod 2 with the diameter of 3m, changing a drill bit 3 with the diameter of 40mm into a drill bit 3 with the diameter of 28mm, and continuously driving the drill bit into the drill hole along the original drill hole to the depth of 2.9 m;

3. changing a 3m drill rod 2 into a 3.5m non-head connecting rod 10, connecting a 1.2m drill rod 2 with a 28m drill bit 3, and driving the drill bit into the hole to 4.6m along the original drilling hole;

4. and keeping the 3.5m connecting rod 10 unchanged, replacing the 1.2m drill rod 2 with the 1.5m drill rod 2 and matching with the 28mm drill bit 3, and driving the drill rod to 4.8m along the original hole.

The small-bore anchor cable supporting technology is widely applied to coal mines, the common drilling equipment is an MQT-120/2.3-C type pneumatic jumbolter, and the drill bit of the pneumatic jumbolter is 28 mm. The drilling machine is mainly driven by rotary friction, and the drilling equipment can meet the requirement on supporting efficiency due to the fact that the hardness of a coal mine layer is low and the drilling machine is easy to break. However, the hardness of the phosphate rock layer and the direct top plate is high, if the drilling machine is directly used for drilling, the efficiency is low, the construction progress is prolonged, the labor intensity of workers is increased, and the construction cost is increased.

In the embodiment, a TY29 type airleg rock drill with higher drilling efficiency in phosphorite is selected, and a 28mm small-sized drill bit of an MQT-120/2.3-C type pneumatic jumbolter in a coal mine is selected as a drill bit. The anchor cable support drilling efficiency is improved, and meanwhile, the quality strength of the small-bore anchor cable support is guaranteed. The innovative combination construction of this mine drilling equipment efficiency improves, and the quality is better, the cost is reduced. Simultaneously, set up spray set 4 and can utilize the water curtain to surround the drilling mouth outside, avoid too much dust to spill over, make the dust fall effect better, protected constructor's healthy.
