该文在理论上对条带开采，首次建立能满足关键层长期稳定存在的关系并在实践中根据留宽已确定的情况，得出了最大理论采宽，实际应用中为增大安全系数，适当缩小采宽进行开采，岩移观测结果表明地表呈现的是单一均匀下沉盆地。 In this paper, the theoretical band mining, the first time to meet the key to the long-term stability of the relationship between the existence and in practice has been determined according to leave wide have been identified, the maximum theoretical bandwidth, the practical application of increased safety factor, Appropriate reduction of mining width mining, rock observation results show that the surface is a single uniform subsidence basin.
