对浅埋煤层进行相似模拟研究并且对采动所产生的开采损害进行实测,利用模型测定上行裂隙与下行裂隙带的发育深度。上行裂隙与下行裂隙是否导通决定着隔水层的隔水性。通过对浅埋煤层覆岩裂隙发育规律进行研究,为浅埋煤层保水开采提供依据。 Similar simulations of shallow coal seams were carried out, and the mining damage caused by mining was measured. The depth of development of the upper and lower fracture zones was measured by the model. Whether the upstream fissure and the downstream fissure conduct the water barrier of the aquitard. By studying the rule of overburden rock fracture development in shallow coal seam, it provides a basis for water-conserving mining in shallow coal seam.
