坪上煤业3号煤上分层矿压显现规律研究

Study on Pressure Manifestation Law of Stratified Coal Mine in No.3 Coal of Pingshang Coal Industry

为了解掌握工作面矿压显现规律,保证工作面正常回采,对坪上煤业Ⅲ1301(上)综采工作面利用科学的电子仪器仪表,采用合理的观测方法对收集数据进行分析,以摸清工作面的矿压显现规律,从而提高液压支架的适应程度和使用效果,改善工作面顶板管理,并为科学管理综采工作面提供依据。

In order to understand and master the law of mine pressure manifestation and ensure the normal mining the normal mining of working face, the fully mechanized coal face of Pingshang coal industry Ⅲ1301(upper) uses scientific electronic instruments and instruments to analyze the collected data by using reasonable observation method to find out the law of mine pressure manifestation in working face, thus improving the adaptability and effect of hydraulic support,improving the roof management of working face, and providing the basis for scientific management of fully mechanized mining face.
