The municipality has 49 kinds of minerals with proved reserves and 218 mineral deposits , and the main minerals include coal , lead , zinc , copper , iron , tungsten , antimony , cement limestone and granite , of which 35 kinds rank top three and 23 kinds top one in the province 全市已探明储量的矿产49种，矿床218个，主要矿种有煤炭、铅、锌、铜、铁、钨、锑、水泥灰岩、花岗石等，其中保有储量位居全省前三位的有35种，居第一位的有23种。
Are about 12 billion tons . the main types of coal are coking coal , gas bituminous coal , lean coal and anthracite , etc . xiangning coal field is one of the three biggest metallurgical coal bases of the whole country , with the characteristics of thick bed , 首屈一指的煤炭资源，储藏面积1 . 54万平方公里，占总面积的5 % ，总储量960亿吨，探明储量120亿吨，主要煤种有主焦煤气肥煤贫肥煤瘦煤无烟煤等，其中乡宁主焦煤为全国三大主焦煤基地之一，而且煤层厚埋藏浅易开采。
Contrarily , the energy consumed per unit of construction area is more than two to three times the amount used in developed countries . the per capita amount of arable land and water resource in china is only one - third and one - fourth of the world ' s average respectively 在我国化石能源资源探明储量中， 90 %以上是煤炭，人均储量也仅为世界平均水平的二分之一；人均石油储量仅为世界平均水平的11 % ；天然气仅为4 . 5 % ；而目前我国单位建筑面积能耗是发达国家的2 - 3倍以上。
The three large fossil plates in china , namely yangtz , tarim , and north china basil plates , are prolific in natural gas with gas resources of 29 . 23 tcm , accounting for 52 . 30 % of the total gas resources in china , and proved gas reserves of 35926 . 8 bcm , accounting for 72 . 2 % of the total proved gas reserves in china 摘要中国三大古板块（扬子古板块、塔里木古板块、华北古板块）天然气资源丰富，三大古板块天然气资源量为29 . 23 10 ^ 12立方公尺，占全国总资源量的52 . 30 % ；三大古板块天然气探明储量为35926 . 8 10 ^ 8立方公尺，占全国天然气总探明地质储量的72 . 2 % 。
And the relationship between the models and type of geological units is derived : gompertz model is suitable for the geological unit with a complex geological setting while exponential model is suitable for the geological unit with a single geological settings and this kind of models can be applied to areas of less complicated geological features 结果表明：两地区累计探明储量与预测探明储量的相关因数均大于0 . 75 ；龚帕兹模型较适用于油气藏类型较多、地质状况较复杂的地质单元，指数模型适用于地质状况比较简单的单元。
This paper predicts the potential of residual resources and unproved reserves in liaohe oilfield , analyzes the exploration degree and direction , evaluates and optimizes each zone , defines 7 key zones for recent exploration in the oilfield , and demonstrates the geological conditions , resource potential and exploration targets in each key zone 运用多种方法对辽河油田剩余资源潜力及近期待探明储量进行了预测，并从勘探程度和勘探方向分析入手，对各个区带进行了深入评价和优选，明确了近期辽河油区的7个重点勘探区带，并对各重点区带的石油地质条件、资源潜力、勘探目标进行了论证分析，为近期油气勘探指明了方向。
There are abundant copper ore resources and mineralization types of copper ore deposits in gansu , china , but the reserves explored is not concordant with of intensity of copper mineralization , which in the providing reserves for important bases of the copper mine productions there is a serious question 甘肃铜矿资源丰富，成矿类型发育齐全。但是，已探明储量与铜矿化强度极不相称；重要铜矿生产基地的资源保障形势严峻。深化区域成矿规律认识与拓宽勘查研究思路尤为重要。
