Abstract: Buried coal seam are discussed in combination with engineering example, a stripe type filling roadway width of coal pillar mining room is decorated in, coal pillar width between lane, lane number and isolation of coal pillar width of coal pillar between the interaction relationship between parameters, such as, calculate the lane between the safety coefficient and isolation of coal pillar width of coal pillar and safety factor; Analysis on the stability of mining interval above the pressure arch, it is concluded that the pressure arch arch and arch foot is the key to its stability, calculating the safety factor of arch and arch foot; According to the strip mining arrangement of production rate and filling rate is deduced formula, and calculate the 28 kinds of roadways and the layout of coal pillar mining rate and filling rate under different filling coefficient. Roadway width, in the end, according to lane between the coal pillar width and number of isolated coal pillar width, the stability of coal pillar, the pressure arch stability and production rate and filling rate of 28 kinds of parameters, such as arranging scheme comparison, recommend meet the reasonable scheme of suitability, stability and economy.
