三聚盛煤业矿井构造特征研究

Study on mine structural feature of Sanjusheng Mine

为了加快三聚盛煤业井田9号煤的采掘需要,在一采区进行开拓基建施工,采用数学统计法与构造分形分维的计算方法,从定量的角度研究矿井构造特征,勘探结果表明,矿井发育4条褶皱构造及5条大中型断裂构造,矿井构造受区域宁武煤田构造控制,以落差小于2 m的断层占矿井断裂总数的61%,小型断裂控制形成矿井主体构造特征,区域构造分维数介于0.55~1.12,一采区分维值较高,构造相对复杂,二采区分维值相对较低,构造简单,矿井主体分维值小于1.0,总体评价矿井构造属简单类型。

In order to speed up the mining needs of No. 9 coal in the operation of Sanjusheng Mine, the construction of infrastructure in a mining area was carried out. The mathematical statistical method and the calculation method of fractal fractal dimension were used to study the structural characteristics of the mine from a quantitative perspective. It showed that the mine developed four fold structures and five large and medium-sized fault structures. The mine structure was controlled by the regional Ningwu coalfield structure. The faults with a drop of less than 2 m accounted for 61% of the total number of mine faults. The small fault control formed the main structural features of the mine. The fractal dimension of the regional structure was between 0.55 and 1.12. The dimension value of the second mining was relatively low, the structure was simple, the dimension value of the mining was higher, the structure was relatively complicated, and the fractal dimension of the mine body was less than 1.0. The overall evaluation of the mine structure was a simple type.
