| 摘 要： | 以酸刺沟煤为工程背景,采用数值模拟和现场实测等方法对6上105-2综放工作面矿压显现规律进行对比分析。研究表明:无煤垛和留煤垛条件下,随着工作面支架支护强度增大,煤壁片帮值和顶板下沉量均减小,相同支护强度条件下,留煤垛开采时,煤壁片帮值和顶板下沉量均较小,工作面支护效果明显优于无煤垛开采。

| Abstract: | Supporting bracket for the study of different intensities gob pile on whether the bar spacing coal caving mining face pressure behavior impact study to Suancigou mine engineering background,the use of numerical simulation and field measurement methods such as 6 上 105-2 caving face different circumstances strata law of comparative research and analysis.Studies showed that: no coal pile and coal pile conditions remain,with face cradle supporting strength of the gradual increase in the value of the coal wall spalling and roof subsidence are gradually declining; same supporting strength conditions,in the coal wall and roof control effect,remain significantly better than non-coal mining pile pillar mining. |
