焦作煤田是国内著名的无烟煤产地。它位于河南省北部,太行山脉南麓的平原边缘上,地势平坦,埋藏丰富,极适于祖国大规模经济建设时期的大量开发。煤系内有许多透水性大的岩层。煤系以上的冲积层和底部的奥陶纪石灰岩透水性也是很大。此外,还有许多断层,不但把煤田分成面积不等的煤块,影响了开采,更严重的是,它是矿井大量湧水的主要通道。通过断层和裂隙,煤层上下各含水层的水,都能很容易地流入巷道,增加了采掘过程
Jiaozuo coalfield is a famous place for producing anthracite in China. It is located in the northern part of Henan Province, on the edge of the plain of the southern foot of the Taihang Mountains. The terrain is flat and rich in burial. It is very suitable for large-scale development during the large-scale economic construction of the motherland. There are many rock layers with high permeability in the coal system. The permeability of the alluvial deposits above the coal measures and the Ordovician limestone at the bottom are also large. In addition, there are many faults, which not only divide the coal fields into coal blocks of different sizes, but also affect the mining. What’s more, it is the main channel for flooding of mines. Through faults and fissures, the water in the upper and lower aquifers of the coal seam can easily flow into the roadway and increase the excavation process.
