The invention discloses a distributed underground reservoir group and a transfer method for mine water in the distributed underground reservoir group. The distributed underground reservoir group comprises more than two underground reservoirs; and the underground reservoirs are respectively connected through water conduit pipelines. According to the distributed underground reservoir group and the transfer method for the mine water in the distributed underground reservoir group, which are provided by the invention, the water conduit pipelines are established among the underground reservoirs and are used for transferring, controlling and centrally draining the mine water in the underground reservoirs, and thus underground water is effectively utilized. Meanwhile, as for the underground reservoirs in different coal seams, the underground mine water is transferred during exploitation, and thus the outside drainage of the mine water during exploitation is avoided and the waste is reduced.

The invention provides a method for detecting and repairing a mine distributed type underground reservoir, which comprises the following steps of: surveying the mine distributed type underground reservoir; analyzing the position with the hidden danger of the underground reservoir according to the survey result; and repairing the position with the hidden danger. The method can be used for surveying the underground reservoir before or when the underground reservoir is in use, the position with the potential safety hazard can be found out in time by surveying the underground reservoir, and the position with the hidden danger can be plugged by grouting, so that the accidents caused by the instability of the structure of the underground reservoir can be avoided, the stable running of the underground reservoir can be realized, and a scientific and reasonable method is provided for protecting the safe running of the underground reservoir.

The invention relates to a purification method of a coal mine distribution underground reservoir water resource. The purification method includes the following steps: (1) separate collection of mine water; (2) filtering and purification of the distribution underground water resource; and (3) circulation filtering and purification of a distribution underground reservoir. The purification method has significant meaning for protection of the underground water resource and can achieve great economical benefit and social benefit. In the aspect of space, the distribution underground reservoir can be formed preliminarily through resource exploiting, water is not required to be sucked out during a coal mining process, coal mining energy consumption is reduced, and water retention mining is achieved. In the aspect of time, even deployment of water utilization can be achieved, and the problem that water utilization is difficult and unbalanced in a mine lot is solved.

The invention relates to a dust collection device for a vibration bed mixed flow dryer. The device comprises a dryer, and at least one primary cyclone dust chamber and at least one secondary cyclone dust chamber which are connected with the dryer through a pipeline in turn; a steam humidifier is arranged in an outlet pipeline on the top of the primary cyclone dust chamber; a sprayer is arranged at an inlet of the secondary cyclone dust chamber; and the dryer is positioned in a micro negative pressure state and has an inner negative pressure value of -90 to -110Pa. A secondary cyclone dedusting and demisting integral structure is adopted, namely different equipment operating parameters and different dedusting processes are adopted for a secondary cyclone dust collection device respectively so as to achieve a two-stage complementary dedusting effect, namely large-particle coal dust is recovered through primary dry cyclone dedusting, and small-particle coal dust is removed through secondary ...

Blasting method of shallow coal seam top plate

Номер: CN103148747A
Автор: Yang Peng, Yang Junzhe, Ren Yanfang, He Anmin, Li Peng, Sun Xiaodong
Принадлежит:

The invention provides a blasting method of a shallow coal seam top plate, which comprises the following steps: (1), a drill hole is formed in a mine mining working surface along a gate roadway, and the position of a rock stratum with the lithological character as an upper roof is determined; (2), a blasthole is drilled in the ground at the back of the mine mining working surface vertically, and the bottom end of the blasthole is arranged in the rock stratum with the lithological character as the upper roof; (3), explosives are filled in the blasthole by adopting a blasthole explosive filling structure coupled in the axial direction and decoupled in the radial direction; and (4) the explosives in the blasthole are detonated. Through the blasting method, the influence on the operation on the working surface is reduced, the surface drilling can be carried out in advance, without losing time, the interference on the underground coalmine production is less, underground operators can evacuate ...
