The waste shaft (W) flowing into the waste shaft is discharged to the lower portion of the waste shaft by the first pipe 100 provided at the lower portion of the waste shaft, and is treated firstly. It is to be prevented that the work efficiency of the forming step (S30) is lowered.

In addition, the waste-rock layer, the first, the second, the third concrete layer and the first, the second, the third clay layer are formed in the interior of the abandoned mine shaft is made to block the outflow of the waste mine in the abandoned mine shaft to the outside.

In addition, the waste shaft made of sedimentation by the primary pipe 100 is introduced into the secondary pipe 200, the waste shaft is discharged to the outside of the waste tunnel through the secondary pipe 200 is filtered by the filter After being made, the filtered waste shaft is discharged to the discharge pipe 750.

Since the waste shaft filtered by the filter is in a state in which impurities and heavy metals are removed by the primary filter and the secondary filter, the waste shaft is recycled into agricultural water or introduced into a river, thereby causing the natural damage to the waste shaft. To be prevented.

According to the method of construction for blocking the waste shaft of the present invention, the inside of the waste shaft is blocked in multiple to prevent the waste shaft from flowing out of the waste shaft, and the waste shaft can be purified to recycle the waste shaft. It works.

In addition, there is an effect of preserving the natural environment of the main surface of the abandoned mine shaft and rivers by allowing the environment to be installed in an environmentally friendly way to block the waste mine shaft to restore the environment damaged by the abandoned mine shaft.

In addition, there is an effect that the sedimentary minerals can be utilized as mineral resources by naturally precipitation the waste shafts dissolved in the leachate and heavy metals and poisons in an environmentally friendly method.

As described above with reference to the drawings illustrated for the construction of the blockage block construction according to the present invention, the present invention is not limited by the embodiments and drawings disclosed herein, but within the scope of the technical idea of the present invention Of course, various modifications can be made by those skilled in the art.
