Current Status and Prospects of Underground Drilling Equipment Technology in Coal Mines
DTH Drilling Rig Supplier shares this article for you. The geological conditions of coal fields are complex, and natural disasters such as gas, water damage, and high ground stress severely restrict coal mine safety production. Underground coal mine drilling construction is the most effective and direct means for comprehensive gas control, mine water hazard prevention, detection of hidden disaster-causing factors, and prevention of rockburst pressure. It is an important geological support technology for coal mine safe and efficient mining. Due to the narrow space of coal mine tunnels and the explosion-proof requirements under special environmental conditions, conventional non-explosion-proof ground drilling equipment and instruments cannot be used directly downhole, and the requirements for underground transportation, ventilation, water supply, and electricity are also directly related to the use and site of drilling equipment The construction has a great impact. The construction...
