1. During the trial excavation of the wellbore, the derrick, the wellhead shed, and the three wells in the well (sealing plate, fixed plate, and hanging plate) should be installed. After the trial is excavated, it can be transferred to the official start.
2. Wellbore lifting and hanging design, the topsoil and bedrock sections should be considered together. After the construction of the topsoil section is completed, the hanging system can be transferred to the bedrock section for necessary adjustment. For example, the wellbore construction with segmented drainage should establish the transfer pump station as early as possible before and after the construction of the manned bedrock section; if there is a strong water-bearing stratum in the bedrock section, the anti-drainage measures should be done in advance, using pre-grouting or Other waterproof measures.
3. From the wellbore to the transitional stage of the construction of the roadway, major adjustments should be made for lifting, transportation, ventilation, drainage and power supply. To this end, the construction organization design of each auxiliary production system for the transitional construction should be completed about half a year in advance, and the construction preparation for various project conversions (including technical preparation, equipment preparation, material preparation, personnel preparation) should be completed, so that the wellbore construction is over. After that, transfer to the smooth road construction as soon as possible.
4. Before the bottom of the main and auxiliary shafts are penetrated, the construction design and preparation work for each system adjustment should be done to ensure the rapid completion of the ventilation, drainage, power supply and transportation system adjustment and the subsequent construction safety.
5. Do the alternate equipment of the mine construction period upgrading system, mainly the construction organization of the main and auxiliary wells alternately, and strive to use the permanent lifting equipment in advance.
