摘要
煤炭是我国重要的基础能源和重要工业原料,在我国国民经济中具有重要的战略地位。在我国一次性能源结构中,煤炭将长期是我国的主要基础能源。我国煤炭资源总体比较丰富,但区域分布不平衡,同时我国人口众多,经济处于在快速发展时期,对煤炭需求量大。近年来煤炭资源急剧减少,已探明的勘探阶段的基础储量严重不足,因此国家对矿产资源的管理、勘查、开发进行调整,对煤炭资源进行整合。煤炭资源勘查的重点也由浅部转向深部,深部资源勘查及地质条件研究已列为当前研究的重要课题。
论文所研究的陕渑煤田仁村东部井田(以下简称研究区)赋存有石炭—二叠系含煤地层及煤层,该区曾进行过地质普查工作,浅部也曾有小煤窑开采,通过普查阶段的钻探物探资料和小煤窑的井下开采揭露显示,该区含煤条件相对邻区要差一些,煤层煤质变化较大,地质条件复杂。因此该区一直没有进一步进行勘查和研究。而邻区仁村西部井田已由义马煤炭集团申请了探矿权,提交了勘探报告。近年来,煤炭资源开发的需要,该区的开发已迫在眉睫,洛阳新安电力集团已申请了该区的探矿权,并委托河南理工大学资环学院对该区资源开发的前景和地质条件进行研究,并提出进一步详查设计的方案。
论文针对研究区进一步开发需要,进一步查明地质条件,依据目前普查阶段的基础资料,通过野外勘测,收集资料,运用煤田地质理论和建立数学模型的量化分析,对研究区的地质条件,煤层厚度变化规律及影响因素进行分析,对控煤构造进行了分析研究,运用等性块段指数法确定研究区的勘查类型,根据对研究区含煤性的分析,认为有进一步详查的必要,提出提高勘查程度的详查设计方案。同时对研究区的开发技术条件(水文地质条件、瓦斯、煤层、顶底板特征)进行初步的分析研究,对煤炭资源开发进行经济概略研究。通过上述研究,为研究区的煤炭资源开发条件提供依据,具有重要的理论意义和生产指导意义。
Coal is important foundation energy and industral material in our country, which has the important strategy position in our country national economy. In our country primary energy structure,Coal will be the main foundation energy of our country in a long time.Coal resources are very rich in our country,but the district distribute is unbalance . Our country has numerous population and economy is placing in fast developing period, which has great capacity in the coal needintg.In recent years ,coal resources sharply decreased.The base reserves of the exploration phase would be a serious shortage. Therefore, the Government adjusted the management、development、exploration of mineral resources, and integration of coal resources. The focus of exploration of coal resources has also shifted from the shallow to deep mineral exploration and geological conditions in the current research are important issue.
The eastern part of Rencun well field in Shanmian Coalfield which is studied in those papers, referred to the study area, has a Carboniferous - Permian coal-bearing strata and coal seams. Geological survey has been done in the area and small coal mines have been mined in the shallow area. Drilling and geophysical datas and underground mining of small coal mines show that Coal-bearing conditions of the area are worse than the adjacent areas.Coal seams and coal quality change a lot, geological conditions are more complex. Therefore, the area has not been further investigation and research,however, the adjacent area Census West has been applied mineral prospecting right and submitted the exploration report by Yima Coal Industry Group.In recent years, due to the need of coal resource development, the developing of the area is imminent, Luoyang Xinan Electronics Group has applied the mineral prospecting right. and has commissioned the institute of Resources and Environment in Henan Polytechnic University to study geological conditions and the area prospects, and design further detailed investigation program.
As the study area needs further development and Geological conditions need be further identified, according to the current stage census data, through field investigation, gathering information, useing coal geological theory and establishing mathematical models of the quantitative analysis, the paper analyses the geological conditions, seam thickness variation reason and its influencing factors , and the structure how to control coal.The paper identifies the survey type of the study area by equivalence block Method, Base on the analysis of coal seam and the coal characters, the paper thinks it necessary to make further detailed investigation, and proposes the detailed investigation design that improves the level of exploration. At the same time,the paper carries out a preliminary analysis of technical conditions for the study area,which include hydro-geological conditions, gas, coal bed, and top floor features, and briefly study economy for the development of coal resources. The paper provides the base of coal resource development conditions, so it has the important significance of theory and guiding production.
