Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the examples, but not as a limitation to the present invention.

[0031] Embodiment of the present invention: a method for spirally disposing of the plugging of the chute, as shown in the attached Figure 1-7 As shown, the method specifically includes the following steps;

[0032] a, there is an adit 1 at the bottom of the chute 2, and a spiral roadway 3 is excavated along the bottom of the chute from the admiralty 1, and the inside of the chute 2 is filled with ore 17 and forms the storage bin 4 of the chute, and the spiral roadway 3 is along the slope of 20%. The chute storage bin 4 inside the chute is driven upwards in a spiral manner, the distance between the inner wall 5 of the spiral roadway 3 and the chute well wall 6 is maintained at a distance of 5 m, and the upper end of the spiral roadway 3 is connected to the upper part of the chute storage bin 4;

[0033] b. In the spiral r...

Abstract

The invention discloses a screw type draw shaft blockage and leakage disposal method. According to the method, a footrill in the bottom of a draw shaft (2) is tunneled upwards in a screw mode along a draw shaft storage bin (4) inside the draw shaft to form a screw type roadway (3), a horizontal hole is formed from the screw type roadway, the blockage and leakage positions are obtained by inserting a rod-like object into the hole, and then blockage and leakage can be removed by placing explosives into the hole and detonating the explosives. According to the screw type draw shaft blockage and leakage disposal method, equipment is simple, the operation cost is low, operation is simple and fast, and the safety is good.

Description

technical field [0001] The invention relates to a mining method, in particular to a method for plugging leakage of a spiral disposal chute, which belongs to the technical field of mining. Background technique [0002] In the field of mining, for mines with long service life, large production scale, medium-sized mines (such as limestone mines, iron mines, etc.) with large mining depth and height difference, in order to make full use of the ore's own gravity transportation, reduce equipment investment in the ore transportation process and reduce operating costs and energy consumption, the use of adit-chute development can greatly reduce ore transportation work, thereby achieving the effect of energy saving and emission reduction, and achieving double harvests of social and corporate economic benefits. For mines that adopt the adit-sliding shaft development method, the ore transportation route is: stope → chute → adit → processing plant, in which the chute is not only used as a...
