大倾角特厚煤层综放工作面工艺模拟试验研究

Study of technique simulating test on fully mechanized top-coal caving workface in greater inclined and thick coal seams

本文针对开滦赵各庄矿3237深部大倾角综放工作面的工艺参数选择,进行了全面的实验室相似材料模拟试验和工作面的对比实测研究,通过多种试验和观测手段与研究方法,获得了大量、丰富的模拟试验数据和研究成果,从而为赵各庄矿3237大倾角综放工作面的工艺参数选择提供了可靠的科学依据。经工作面开采的实践表明,实验室相似材料模拟试验的工艺研究结论是正确可靠的,该方法完全可以作为综放工作面工艺参数选择的重要实验手段。

This paper carries out an overall similar materials simulation test within a laboratory,contrast to actual measured study of workface with technique parameters selection on fully mechanized top-coal caving in workface 3237 of Zhaogezhuang coal mine in Kailuan with greater inclined and deep mining situation.We have obtained a large number of data and achievements through several methods of testing and observation,to provide reliable references to technique parameters selection on fully mechanized top-coal caving in workface 3237 of Zhaogezhuang coal mine.This technique studies have indicated that it is reliable to prove through practicing in mining of workface and similar materials simulation in laboratory.This method can be used as an important measure of technique parameters selection on fully mechanized top-coal caving.
