In 2017, China revised the articles of Association for the retention and coal pressure of coal pillars in buildings, water bodies, railways and main shafts and lanes. By summarizing the observed results, the empirical formula for calculating the height of water diversion fracture zone and caving zone is put forward. Taking Bayi mining area of Xinhu coal mine as an example, the empirical formula is reasonably selected through the coal seam overburden conditions, coal seams and interlayer conditions in the mining area. The height of “two zones” is calculated to provide a basis for the retention of coal and rock pillars. %K “三下”规程,经验公式,导水裂隙带,冒落带
