male, associate research fellow, master’s supervisor. He graduated from China University of Mining and Technology in 2014 with a master’s degree in Mining Engineering. He currently works at China Coal Technology & Engineering Group Shenyang Research Institute, where he is primarily en-gaged in the prediction and prevention of coal‑rock dynamic disasters. He is a nationally registered safety engineer in China. He was selected as a “Liaoning Provincial Hundred‑Thousand‑Ten Thousand Talents” in 2020. He is a member of the China Coal Society.
Based on the determination of basic parameters of coal‑rock strata and gas, the author has investigated the gas occurrence and emission patterns in coal seams under complex geological conditions, and carried out regional pre-diction of outburst hazard. He has experimentally studied the fracture initi-ation and propagation laws of hydraulic fracturing in coal‑rock masses, and applied directional hydraulic fracturing through pre‑cut slots and three‑dimensional rotating water jets to solve problems such as permeability enhancement in low‑permeability seams, outburst elimination in hazardous seams, and rock burst control. He has achieved a series of scientific and technological achievements, including gas emission laws and comprehensive control technologies for rock burst coal seams, integrated prevention tech-nologies for rock burst, gas, coal dust, and spontaneous combustion in deep high‑stress areas, and fine‑enhanced gas pre‑drainage technology based on a dynamic gas‑geology analysis system.
