英语翻译
如图可知,地形剖面图符号少,属于水平岩层,各岩层与煤层排列规则,新老顺序交替正常,地形切割不明显,地表出露岩层单一,煤层形态和厚度变化较小.
如图可知,地形剖面图图面较复杂.地形切割明显,属倾斜岩层,层面与参考水平面有一定交角,存在背斜、等斜褶曲的地质构造.煤层形态和厚度变化较大.
数据显示表明,中国每生产百万吨煤炭死亡0.5个矿工,美国每生产百万吨煤炭死亡0.03个矿工.
总而言之,中国南方的煤层大多随着围岩经历多期构造运动,其原始分布状态被强烈改造过,经常呈倾斜状态或者被断层穿过、错断,中国南方的煤炭储层地质条件复杂,开采难度较大,井下作业风险高.美国的煤层没有经历多期构造运动的强烈改造,经常是近水平状以原始的状态分布,煤层产状比较简单,煤炭储层开采风险较低.

Answer 1

As shown in figure, the terrain profile symbols, simple drawings.Belong to the horizontal stratum, the strata and the rules of coal seam, the new and old order normal alternately, terrain cutting is not obvious, single surface outcropped strata, coal seam shape and thickness changes small.
As shown in figure, the terrain profile drawings more complex.Terrain cutting, tilted strata, with level a reference level crossing Angle, anticline, isoclinal fold of geological structure.The variation in thickness of coal seam shape and large.
According to data show that China's 0.5 death every production one million tons of coal miners, the 0.03 death every production one million tons of coal miners.
To sum up, most of the coal seam in southern China with experienced multiphase tectonic movement of surrounding rock, its original distribution is strongly modified, often in tilt state or fault through, disconnected, in southern China coal reservoir geological condition is complex, drilling is difficult and high risk in underground work.Coal seams in the United States experienced multiphase tectonic movement of intense transformation, often is nearly horizontal to the original state distribution, coal seam occurrence is simpler, the coal reservoir exploration risk is low.
