象山矿井涌水量相关因素分析

为探究生产状况等因素对象山矿井涌水量的影响,收集整理象山矿井生产以来的矿井涌水量资料,从地质及水文地质条件出发进行了详细分析,并对涌水水源进行了分类。通过初步研究可知,地质条件与采矿活动是影响矿井涌水变化的主要因素,地质构造和含水层厚度对矿井涌水起到了主要控制作用,而涌水水源主要为老空水,该涌水量变化主要与矿井采空区留设了疏放水钻孔标高和疏水时间有关,另外矿井向斜地质构造对矿井涌水的变化产生了叠加影响。通过分类分析,为矿井采区工作面以后的涌水量预计提供了可借鉴的科学依据。

Analysis of relevant factors of water inflow in Xiangshan coal mine

In order to explore the influencing factors of water inflow in Xiangshan mine,the data of water inflow since the production of Xiangshan mine were collected,the geological and hydrogeological conditions of the mine were analyzed,and the water source of water inflow was classified.The research shows that the geological conditions and mining activities are the main factors affecting the change of mine water inflow;the geological structure and aquifer thickness have the main control effect on the mine water inflow;the mine water inflow source is mainly the goaf water,and the change of the water inflow is mainly related to the elevation and drainage time of the drainage borehole reserved in the mine goaf,in addition,the mine syncline structure has the superimposed effect on the change of the mine water inflow.The research provides a scientific basis for the prediction of water inflow in the mine and working face.
