论文中文摘要:
近年来,由于产能过剩、新能源等产业快速发展,共同挤压了煤炭的生存空间。我国煤炭企业正面临兼并、整合重组、减少产能境况。但是我国能源结构单一,煤炭仍是我国经济发展不可缺少的能源基础。因此,更需要我们安全、高效的开采。象山煤矿地质条件特殊、复杂。因此,深刻认识矿井地质构造客观规律,准确评价矿井构造复杂程度,为煤矿选择合理开采工艺以及资源高产、高效开采提供科学依据。 论文通过对研究区区域构造背景分析、认识的基础上,总结了矿区断层、褶皱构造的展布规律以及岩浆活动规律,在此基础上进一步分析象山煤矿地质构造的发育特征及发育规律。然后应用模糊综合评判,对象山煤矿已采区构造发育复杂程度进行综合评判;根据在全区可获得的指标应用灰色理论预测未采区各指标的参数值,并对未采区构造复杂程度进行评价。论文研究取得以下结果: (1)象山煤矿在北采区与南一采区共揭露断层192条,其中3号煤层揭露断层170条,断层密度60.6条/km2,5号煤层共揭露断层22条,断层密度36.6条/km2,除个别断层外,几乎所有煤层断层全部为正断层。断层走向以北西NW向占绝对优势,其次为近东西EW向和北东NE向,近南北SN向较少,断层落差以1~2m最多,其次为2~5m。大于5m的中型断层21条,其中最大断距14.2m。 (2)井田3号煤层内共发育褶皱构造14条,5号煤层共发育褶皱构造15条。褶皱两翼媒岩层倾角一般介于2.5~8.8°之间。基本属于开阔平缓褶皱,轴长变化于400~3500之间,宽度变化于350~1550m,背、向斜相间出现,除个别褶皱幅度达到20m外,其余均在20m以下,多数为5~10m的宽缓小型褶皱。轴向以北西NW向与东西EW为主,次为北东NE向。 (3)利用模糊综合评判,对象山煤矿已采区划分为55个单位进行评判,结果为:属于Ⅰ类构造的有43个单元,属于Ⅱ类构造的有6个单元,属于Ⅲ类构造的有4个单元,属于Ⅳ类构造的有2个单元,评价结果与实际开采揭露情况对比基本吻合。对未采区各单元构造复杂程度类型作出了综合评判,结果为:未采区所分的41个单元中,属于Ⅰ类构造的有8个单元,属于Ⅱ类构造的有31个单元,属于Ⅲ类构造的有2个单元,故未采区构造复杂程度为较简单。
论文外文摘要:
In recent years, because of excess production capacity, the new energy industry fast development, that squeezed the survival space of the coal. Coal enterprises are facing mergers and restructuring, reduce capacity situation. But a single energy structure in China, coal is still indispensable to the economic development of our country energy base. Therefore, more need to us safe and efficient mining. Xiangshan coal mine geological conditions is special and complicated . Therefore, the deeply understanding of mine construction objective laws, accurate assessment of mine structure complexity, choose reasonable for coal mining technology, and provide a scientific basis for high yield, high efficient mining resources. Paper through the analysis of regional tectonic background of the study area, and summarizes the mining fault structure structural and magmatic activity rule and fold, on the basis of further analysis of xiangshan coal mine geological structure development characteristics and law of development. Then using fuzzy comprehensive evaluation, evaluation of xiangshan coal mine construction development complexity; Grey theory is applied to forecast the mining area estimation parameter values, and to evaluate not mining area. Thesis research come to the following results: (1) there were revealed fault 192 in south of the first mining area and north mining area in xiangshan coal mine, exposed fault is 170 in no. 3 coal seam i , fault density is 60.6 / km2, 22 fault were revealed in no. 5 coal seam, fault density is 36.6 / km2, in addition to the individual fault, almost all of the coal seam faults are all normal fault. faults to the north of the west to the dominant, followed by something nearly to the north and east , near the north and south to less, most fault throw in 1 ~ 2 m, the second is 2 ~ 5 m. Greater than 5 m medium fault article 21, the biggest fault throw is14.2 m. (2) in the no. 3 coal seam mining field, a total of development fold structure article 14, article 15 in no.5 coal seam, a total of development to the fold structure. Fold two coal strata dip Angle generally between 2.5 ~ 8.8 °. belong to open gently fold, axial length changes between 400 ~ 3500, the width of the change from 350 to 1550 m, Anticline and syncline appear alternately, in addition to the individual fold amplitude up to 20 m, the rest are under 20 m, mostly small fold is 5 ~ 10 m wide. EW and EW is given priority to, time for NE. (3) the use of fuzzy comprehensive evaluation, the xiangshan coal mine has been is divided into 55 units of evaluation, the result is: the belongs to Ⅰ class structure has 43 units, belong to Ⅱ class structure has 6 units, belong to Ⅲ class structure has 4 units, belong to Ⅳ class structure has 2 units, the evaluation results compared with the actual mining revealed. Structural complexity of the units of mining area not type has made a comprehensive evaluation, the result is: 41 points by unit, not mining area belongs to Ⅰ class structure has 8 units, belong to Ⅱ class structure has 31 units, belong to Ⅲ class structure has 2 units, so not mining area is relatively simple structure complexity.
