摘要
为评价较大区域塌陷发育特征和危害程度,在调查15个煤矿采空区的基础上,按城区、乡镇、村庄和农田荒地四个不同区域,建立塌陷危害程度分级标准。并以此标准对郑煤米村煤矿进行危害程度分区,绘制大比例尺塌陷危害分区图。同时针对不同的分区及其塌陷危害程度,提出相应的塌陷治理措施。
Based on the survey of 15 coal mining areas,grading standards of damage degree are set up respectively for the city,towns,villages and farmland wasteland,to assess development characteristics and damage degree in a rather big region.These standards are used to divide the Micun coalmine into sub-zones and draw a large-scale zoning map for it.And control measures are proposed for the different sub-zones according to their harm level.
