煤层所遭受的构造变动是影响煤矿生产最重要的地质因素之一。为了保证采掘工作的顺利进行,地质工作不仅应该准确地查明已发现的各种构造形迹;而且最好能在巷道未揭露前就预先提出可能出现的构造变动。特别是随着采掘机械化程度的不断提高,液压支架联合机组使用以后,就更需要预见采区、采面内将要出现的各种构造形迹,以便及时采取措施,保证生产正常进行。
Structural changes affected by coal seams are one of the most important geological factors that affect coal production. In order to ensure the smooth progress of the excavation work, the geological work should not only accurately identify the various structural features that have been discovered, but also make it possible to advance the possible structural changes before the roadway is exposed. Especially with the continuous improvement of mining mechanization, after the use of the hydraulic support combined unit, it is even more necessary to predict various structural features that will appear in the mining area and mining face in order to take timely measures to ensure normal production.
