(1) Pioneering work (2) The purpose of development: [Bottom yard] The bottom yard is the general name for some diverticulum and roadway near the wellhead (such as: water tank, pump house, underground substation, etc.). [Stone Gate] The wellbore leads to the roadway where the ore bodies that need to be mined are excavated. [The main diverticulum in the underground] refers to the underground gunpowder warehouse, the underground broken chamber, the mine chamber, and the machine room. [Note] 1) The pedestrian system must ensure that there are at least two safety exits so that personnel can enter safely, up and down, and have good pedestrian equipment. 2) The difference between the main and auxiliary roadways is that the roadway that carries the ore is called the main roadway.

The significance of pioneering work means: to dig a series of roadways from the ground to reach the ore body, so that the ore body connects to the ground, forming a system of pedestrian, ventilation, transportation, drainage, power supply, air supply, water supply and so on. 1 transporting the ore waste rock to be produced underground to the surface
2 Discharge waste water and dirty air to the surface 3 Transport personnel and advanced materials to the underground for production (3) Develop roadways – Lanes that are built to achieve the above-mentioned pioneering purposes are called open roadways. For example, wellbore (shaft, inclined well), Pingyi, Shimen, bottom hole yard, underground stone day room, main stage transportation roadway, main mine, filling well, etc., all belong to the development of roadway.
Mining steps of the deposit - pioneering work
Step metal deposits underground mining can be divided into: exploration, mining accurate, and actual mining cut four steps that reflect different stages of work.
