冲积层

• In order to accurately calculate the mining induced subsidence in thick alluvium areas so as to decrease the mining damage and environment disruption , the calculation of surface subsidence caused by water loss of clay was discussed based on probability integral method and used in a real case
  摘要为了更加精确地计算厚冲积层矿区的煤矿开采沉陷问题，减小采动损害与环境破坏，基于煤矿开采沉陷计算的概率积分法，探讨了由于黏土体失水引起的地表沉陷计算问题，推导了黏土体失水引起的地表下沉计算公式，并应用于煤矿实际地表沉陷，加以分析论证。
