摘要
煤层厚度是影响煤矿开采工艺及采场选择的主要因素之一。3~#煤层作为下峪口煤矿的主采煤层,具有厚度大、变化也大的特点。总结了3~#煤层的厚度变化规律,从沉积环境、地质构造以及后期河流冲刷等影响因素分析了造成煤层厚度变化的原因,对指导煤矿预测及合理开发3~#煤层具有一定实践意义。
Coal seam thickness is one of major factors in the effect of well body stress on coat-mining and choosing stopes. No.3 coal seam as the primary mineable coal seam in Xiayukou coal mine, has the characteristics of big thickness and changes. The changing law of No.3 coal seam thickness is presented and the factors is analyzed, which resulted from sedimentary environment, geologic structure and later river erosion,which results will have practical significance in guiding forecasting in coal mine and rational exploitation No.3 coal seam.
