(I) Optimize the construction plan and adopt advanced construction technology Mining engineering construction technology is also progressing with the development of science and technology. Optimizing the construction plan or adopting advanced construction technology can effectively shorten the construction period. For example, the construction of the topsoil of the wellbore can ensure that the wellbore passes safely through the topsoil to avoid construction safety accidents. The deep deep freezing construction of the wellbore can effectively ensure that the wellbore passes through the bedrock aquifer smoothly, ensuring the planned construction period of the wellbore, and avoiding the possibility of delays in construction due to the water treatment of the wellbore. The roadway construction adopts the bolting and shotcreting support technology to replace the traditional masonry support, which greatly reduces the labor intensity of the workers, speeds up the construction progress and saves investment. In the installation work of the ground lifting equipment, the elevator control system selects advanced automatic control technology. Although the initial investment is large, it can save the installation period and its long-term economic benefits are significant.
(II) Improve the construction process and shorten the technical gap time of the process. There are many varieties of mining engineering construction projects, continuously improve the construction process, shorten the technical gap time between processes, shorten the total construction time, and achieve the purpose of shortening the total construction period. For example, the construction of the inner wall of the inner section of the freezing section of the wellbore has been widely promoted in the past. Because of the need to specially manufacture the sliding die plate, and the continuous operation in the slipform construction, sometimes the construction is difficult to guarantee, and the delay time often occurs. phenomenon. By continuously summing up experience and improving the wall-covering process, the construction enterprise adopts the block-mode switching construction method, and on the basis of strictly controlling the initial setting time of the concrete, realizes the continuous construction process of the block-die transformation of the inner wall of the frozen section, and shortens the wall-covering time. The construction period is saved and the construction speed of the frozen wellbore is accelerated.
(III) Adopting more advanced construction machinery and equipment to speed up the construction speed The main processes of mining engineering construction have basically achieved mechanization, and the selection of advanced and efficient construction equipment can fully exert the performance of mechanical equipment and achieve the purpose of speeding up construction. For example, in the construction of the bedrock section of the wellbore, the traditional manpower operation rock loader is used, and 6~8 people operate. The slag discharge efficiency is only about 20m3/h, and the advanced central slewing rock grabber only needs 1~2 The operation efficiency of the slag can reach 50m3 / h, which not only saves manpower, but also speeds up the slag discharge. Another example is the coal roadway excavation work, especially the long-distance roadway excavation. The traditional drilling and blasting method construction speed is only lOO~200m/month, and the coal roadway comprehensive excavation machine is used for excavation, the average can reach 300~500m/month, the most Fast up to lOOOm / month.
Therefore, the use of more advanced construction machinery and equipment is an effective guarantee for speeding up the construction progress of mining projects.
