潘三煤矿构造地质条件复杂,断层、褶曲、火成岩、陷落柱均发育,且由于矿井10多年的高强度开采,采空区面积大、积水水头高,而下阶段工作面出于防突需要多为沿空布置,从而增加了防治、探放老空水的难度。围绕影响矿井安全高效开采的主要地质因素,采用了地面与井下、钻探与物探相结合的综合探测方法,构建了适合潘三煤矿安全高效开采的地质保障技术体系。
Pansan Coal Mine is characterized by complex geological conditions, faults, folds, igneous rocks and collapse columns. Due to the high-intensity mining in the mine for more than 10 years, the mined-out area is large and the water head is high. However, Mostly arranged along the sky, thereby increasing the prevention and control, exploration of old empty water difficult. Aiming at the main geological factors that affect the safe and efficient mining of mines, a comprehensive exploration method combining ground and well, drilling and geophysical exploration was adopted, and a geological protection technology system suitable for safe and efficient mining in Pansan Coal Mine was constructed.
