摘要
为了分析煤层群同采工作面合理错距,通过理论分析认为同采工作面采用稳压式布置比较合理;采用物理相似模拟实验,研究其煤层超前工作面支承压力对工作面合理错距的影响;然后,综合矿压理论和实验结果,综合修正了下煤层初采和正常同采时的合理错距,即下伏3-1煤和4-2煤初采合理错距应为84.8 m和79.3 m;3-1煤和4-2煤正常同采时的合理错距应不小于40 m和46 m。
In order to analyze the reasonable distance between the coal seam group and the working face. Through theoretical analysis with the use of mechanized Face Regulator - style layout is reasonable. Similar experiments using physical simulation, Advance study seam Face to Face reasonable abutment pressure from the wrong influence. Then, mine pressure combined theoretical and experimental results, Comprehensive Fixed error under reasonable and normal initial mining coal seam mining at the same distance. That is, the underlying coal 3 -1 and 4-2early coal mining should be reasonable distance during 84. 8m and 79.3m. 3 -1 coal and 4 -2 coal mining wrong when normal with reasonable distance not less than 40m and 46m.
