Key route for construction of mine roadway

1. The composition of the key route of mine roadway engineering In the mine roadway engineering, some of the coherent projects constitute the longest project in the whole mine construction, which forms a key route. Such as wellbore→bottom yard heavy-duty line→main stone gate→transportation alley→ mining area yard→ mining area uphill→ last mining area cutting roadway or wind tunneling roadway. The key route of the mine roadway determines the construction period of the mine.
2. Main methods for shortening the key route of the roadway engineering (1) If there is a wind well at the mine boundary, the main auxiliary shaft and the wind shaft can be digged in the head, and the through point is arranged at the junction of the transportation lane and the mountain.
(2) Where conditions permit, the measures can be excavated to shorten the length of the main contradiction line of the wells. However, it must be jointly studied by the construction and design units and submitted to the design approval unit for review and approval.
(3) Reasonable arrangement of project start-up sequence and construction content should actively adopt long-term and parallel cross-operation.
(4) Strengthen the allocation of resources, and put the construction teams with key teams and technical strengths on the main contradiction line construction.
(5) Do a good job in the construction preparation of various major contradictions on the line, give priority to personnel, equipment and equipment, and create the necessary material conditions for the uninterrupted construction of the main contradiction line.
(6) Strengthen the comprehensive balance of the main contradiction line construction, do a good job in the connection of various processes, solve the weak links, and reduce the auxiliary time to a minimum.

Spare Parts

We provide the most complete range of spare parts, guaranteeing that each one is the original production, brand new unused

The blades of the Concrete Mixer play an important role in the operation of the mixing plant. In the composition of the ladder concrete mixer, the mixing drum, mixing drum, blades, etc. are all important components. Then, in the production process, the mixing operation of these spare parts can ensure the production quality of the concrete mixer. However, if any one part is not well matched during the production process, it can cause many problems and even lead to the failure of the concrete mixer.

Spare parts are an integral part of machinery. When the machine is running at high speed, especially after years of accumulation, there will be inevitable losses. At this time, we need to replace the parts of the machine to ensure the normal operation of the machine.
