(1) Increasing the working face and organizing more construction teams to deal with the characteristics of the number of mining projects. In the preliminary preparation work, the construction team can be targeted for different wellbore to ensure the preparation work around the wellbore. successfully launch. When the wellbore is transferred into the roadway and the diverticulum, under the conditions of improving transportation, ventilation and drainage, open the working surface as much as possible and organize the parallel construction of multiple working faces. For ground civil works, if there are conditions for independent construction, arrange the construction team as much as possible.
In the later stage of mine construction, the installation work has become the main contradiction. It is necessary to create more work surfaces to arrange the construction team to carry out the installation work, and to organize the parallel operation to the maximum extent under the condition of permitting, which can effectively shorten the total construction of the mine. Duration.
(II) Increasing the construction operation time For the key projects of the mining project, uninterrupted construction should be arranged. For the process that has a delay, the next key work should make full use of the time and work overtime. Such as ground installation works, in the case of tight time, you can extend the daily working hours, or arrange night shift operations, shorten the actual number of installation days, to achieve the purpose of shortening the construction period.
(III) Increasing labor and construction machinery and equipment To effectively shorten the duration of work, the number of labor force can be appropriately increased, especially the labor-based process. For example, if the mechanical equipment can not function, if the working surface permits, the labor can be arranged to excavate the frozen soil, which can effectively speed up the slag discharge and improve the construction progress of the frozen section of the wellbore. Shorten the working time of the wellbore, so as to shorten the construction period. During the construction, the number of construction machinery and equipment can be increased when conditions are met, and the working efficiency of the working surface is greatly improved. For example, if the slag is discharged from the bedrock section of the wellbore, if there are 2~3 buckets in the wellbore and only one rock grabbing device, the slag speed is difficult to guarantee. If the shaft section allows two sets of rock grabbing equipment to be arranged, the slag can be effectively improved. Speed, which is very effective in speeding up the construction of the wellbore.
Gas Orifice is an essential part for gas appliance. Its main function is adjusting the gas flowrate, which directly effect the working condition of burning.
Gas orifice are of two types: convergent and divergent.
The convergent-divergent gas orifices are therefore used to accelerate the fluid which is choked to supersonic speeds in the convergent sections. This process is considered to be more efficient than making the convergent gas orifice to expand externally. The gas orifice are of different types and are commonly round tubes used to perform different functions.
The material is copper, brass, stainless and aluminized steel. Covered area and spraying effect can be adjusted, it can be adjusted to the artificial fog, flat fog effect, simple atomizing effect, which require a low water pressure with far range.
