The ordinary well drilling method generally adopts a construction method mainly based on rock blasting.
In order to ensure the normal construction of the mine construction, avoid the phenomenon of stoppage and work, and create the necessary conditions for the workers' lives, construction preparation work before the construction of the well must be done. The construction preparation period and the construction period (called the construction period) calculated after the start of the wellbore together constitute the total construction period of the mine. The construction preparation period is usually 0.5~1 year. The main contents of the construction preparation are shown in the table.
There are many work in the preparation period. Mine construction, Shi Jian, installation of three major projects in parallel, between various types of work processes and cross frequently, in order to accelerate construction preparation and the rational use of capital, labor, and other applications integrated approach to the preparation of the reasonable period of project preparation plan.
