| 摘 要： | 针对现有的开采沉陷预计的剖面函数具有表达式过于复杂,坐标原点、参数在实际使用时较难确定等缺点,研究矩形采空区上方地表沉陷观测数据的特征,提出一种新的开采沉陷预计的主断面拟合函数。这种新的拟合函数表达式简单,在实际工作中容易确定相关参数。某矿山的实测资料验证说明,提出的拟合函数与实测资料吻合程度较高。

| Abstract: | The existing section function for mining subsidence prediction has several shortcomings,such as complex expression,uncertainty of coordinates origin and parameters in application.The features of observing data in the ground subsidence of rectangular goaf are studied and a new fit function of main section is proposed for mining subsidence prediction.This new function has some merit that the mathematical formula is simple and the parameter is also easy to identify in practices.It is proved that the results of... |
