【摘要】：本论文以冀中能源峰峰煤焦化有限责任公司城镇煤矿IV13煤层201综采工作面为工程背景,通过计算机数值模拟和现场实测等研究方法,对大倾角煤层在开采过程中工作面矿压特征以及围岩控制技术进行了研究。通过对不同倾角的煤层开采进行计算机数值模拟,研究大倾角煤层在开采过程中工作面走向与倾向的垂直应力分布规律以及大倾角煤层综采工作面在开采时的矿压显现特征。根据现场实测,分析研究大倾角煤层在开采时的矿压显现规律;通过收集资料,阅读相关的文献书刊,应用相关的理论知识,分析研究大倾角煤层开采的矿压特征以及工作面围岩的运移规律。以获得的大倾角煤层在开采时工作面矿压显现特征为基础,同时对大倾角综采工作面设备的稳定性及201综采工作面设备选型进行分析研究,提出大倾角煤层的围岩控制技术。
[Abstract]:This paper takes IV13 coal seam 201 fully mechanized mining face of town coal mine of Jizhong Energy Fengfeng Coal Coking Co., Ltd. As the engineering background, through computer numerical simulation and field measurement and other research methods. The characteristics of face pressure and surrounding rock control technology in mining process of large dip coal seam are studied. Through the computer numerical simulation of coal seam mining with different dip angles, the vertical stress distribution law of the working face and its tendency in the mining process of the large dip coal seam and the characteristics of the rock pressure behavior of the fully mechanized coal mining face with the large dip coal seam during the mining process are studied. According to the field measurement, this paper analyzes and studies the law of rock pressure behavior of large dip coal seam during mining. Through collecting data, reading relevant documents and periodicals, and applying relevant theoretical knowledge, the characteristics of mining pressure of large inclined coal seam and the migration law of surrounding rock of working face are analyzed and studied. Based on the characteristics of rock pressure in coal face in mining, the stability of equipment and the selection of equipment in 201 fully mechanized coal face are analyzed and studied, and the control technology of surrounding rock in large dip coal seam is put forward.
