Abstract: Coal reserves explored are very rich in Lingtai mining area. The mining technical requirement in Anjiazhuang Filed included in Lingtai mining area was analyzed, and some recommendations were provided. The paper has guiding significance for coal resources mining in Lingtai mining area. The stability of the surrounding rock of the laneway construction is poor. The lithology of main coal seam (No. 8-2) roof were mudstone, sandy mudstone and carbon mudstone, the mainly type of seam roof was extremely unstable and unstable. There were high stresses and rock bursts could easily occur during mining due to the coal’s deep occurrence. Anjiazhuang mine should be designed as a high gas mine. The coal dust was combustible and explosible. The temperature was above 37℃ in most of mining field. Therefore, the mining conditiongs were complicated.
Key words: Lingtai mining area, coal resources, mining technical requirement, stability of seam roof
