大倾角构造复杂煤层开采技术研究
|
摘要
在我国随着原煤产量的不断增加,构造复杂煤层所占比重逐渐增加。由于地质构造条件复杂,导致煤层赋存的不规则,无煤带、薄煤带、厚煤区相继出现,给煤矿生产管理、资源安全生产和有效回收,带来很多待要解决的问题。
本论文以大安山矿+680m水平后槽构造复杂煤层为研究对象,通过理论分析、三维建模等方法查明构造与煤层赋存状态;应用MICROMINE软件计算得出煤层储量;通过数值模拟对水平大巷布置方式进行分析,确定岩石水平大巷布置;提出单体柱加柔掩支架在开采大倾角煤层条件下的支护特性、开采技术参数、回采工艺和安全开采技术方案,提高了回采率。为今后在类似条件下进行找煤和回采提供了重要的依据。
The proportion of the complicated coal seam is enhancing gradually with the increase of the coal output in China. The thin coal, thick coal, and no coal zero caused by the coal seam irregular because of the complex geological conditions especially to the geological structures, appear alternately, which brings questions of the product management, the safe production and the effective resources recycle.
According to the complicated coal seam of structure of +680m level mining area in the Da'anshan mine, the methods of theory analysis and 3D simulation have been used to research the characteristic of the geological structure terms and coal seam. Then the reserves is calculated by the MICROMINE software. At the same time, the arrange way of rock’s tunnel is confirmed basised on the numerical simulation. In the end, the support characteristic, the technical parameters, the mining methods and the safe exploiting technology of flexible shield supports have been determined under the coal seam with deep dip angle. The rate of extraction is improved accordingly. These will provide an important basis for the coal seeking and exploiting under the similar condition hereafter.
