| 摘 要： | 结合数值模拟和现场实测探讨了薄煤层综采工作面对煤壁前方的影响范围及其分布规律。由于采高较小,初次来压和周期来压显现不明显,需用连续记录仪和现场人员及时观察才能对煤壁前方影响范围准确确定。通过研究得到对前方煤壁较强烈的影响范围为距离煤壁1～6m,对前方煤壁的影响范围为距离煤壁约为16m。

| Abstract: | Numerical simulation and field measurement of a thin seam coal mining face of the wall in front of the scope and distribution.As mining height small initial pressure and pressure cycle to appear obvious,needed a continuous recorder apparatus and observe the scene in a timely manner to the extent of coal accurately determine the front wall.More strongly on the front wall of the iMPact of coal range from the coal wall 1 ～ 6m,on the front wall of the range of coal from the coal wall is about 36m. |
