s time for the wild fruits to ripe. The picturesque Arxan in Autumn is indeed a fairyland only exists in a dream that satisfies all your fantasies. If it rains heavily on Saturday night, some elderly Chinese will say it is because Zhinu, or the Weaving Maid, is crying on the day she met her husband Niulang, or the Cowherd, on the Milky 安徽理工大學畢業(yè)論文 Way. Most Chinese remember being told this romantic tragedy when they were children on Qixi, or the Seventh Night Festival, which falls on the seventh day of the seventh lunar month, which is usually in early August. This year it falls on Saturday, August 2. Folklore Story As the story goes, once there was a cowherd, Niulang, who lived with his elder brother and sisterinlaw. But she disliked and abused him, and the boy was forced to leave home with only an old cow for pany. The cow, however, was a former god who had violated imperial rules and was sent to earth in bovine form. One day the cow led Niulang to a lake where fairies took a bath on earth. Among them was Zhinu, the most beautiful fairy and a skilled seamstress. The two fell in love at first sight and were soon married. They had a son and daughter and their happy life was held up as an example for hundreds of years in China. Yet in the eyes of the Jade Emperor, the Supreme Deity in Taoism, marriage between a mortal and fairy was strictly forbidden. He ordered the heaven troop to catch Zhinu back. Niulang grew desperate when he discovered Zhinu had been taken back to heaven. Driven by Niulang39。 ll wait in the line for one hour to get a ticket, and another two hours at the site, to only see a tiny bit of the place due to the crowds. Last year, 428 million tourists traveled in China over the weeklong holiday in October. Traveling during this period is a matter that needs thorough preparation. If you are short on time to plan the uping Golden Week it may not be a bad idea to avoid some of the most crowded places for now. There is always a place so fascinating that everyone yearns for. Arxan is a place like this. The beauty of Arxan is everlasting regardless of the changing of four seasons. Bestowed by nature, its spectacular seasonal landscape and mountains are just beyond word. Arxan is a crucial destination for the remended travelling route, China Inner Mongolia Arxan — Hailar — Manzhouli. It is also the joint of the four prairies across the SinoMongolian border, where people gravitate towards the exotic atmosphere mixed with Chinese, Russian, and Mongolia elements. As a historic site for the Yitian Battle, Arxan still embodies the spirit of Genghis Khan. Walking into Arxan, you will be amazed by a kaleidoscope of geous colors all the year round the Spring azaleas blooming red in the snow, the Summer sea wavering blue in the breeze, the Autumn leaves painted in yellow covering volcanic traces, and the Winter woods shining white on the vast alpine snowscape. Hinggan League Arxan city is situated in the far eastern area of Inner Mongolia Autonomous Region. Its full name Haren Arxan means hot holy water in the Mongolian language. Arxan is a tourism city in the northern frontier with a blend of large forest, grand prairies, vast snowfield, heaven lake cluster, thermium, as well as volcanic cluster. It is a rare and unique ecotourism base filled with healthy sunshine, clean air and unspoiled green. Nestled close to the country39。 在整篇論文的編寫期間,從選題,資料的收集、整理,再到論文的撰寫編排,再到論文的完成, 我感覺自己對這個專業(yè)的了解認識又到了新的層次。Geomech, 1981, 18(4):267 [4] 程裕淇 .中國區(qū)域地質(zhì)概論 [M].北京:地質(zhì)出版社 .1994 [5] 劉程,李向東,楊守國 .地質(zhì)構造對煤層厚度的影響 研究 [J].煤礦安全 ,2022,5:1416 [6] 彭華 .地質(zhì)統(tǒng)計法在煤層穩(wěn)定性定量評價中的應用 [J].山西煤炭 ,2022,22(2):5153 [7] 舒良樹,吳俊奇,劉道忠 .徐淮地區(qū)推覆構造 [J].南京大學學報 ,1994,30(4):639648 [8] 王恩營,邵強,王紅衛(wèi) .華北板塊晚古生代煤層構造煤區(qū)域分布的大地構造控制及演化 [J].西安科技大學學報 ,2022,26(2):193195 [9] 薛喜成 .南桐礦區(qū)硯石臺煤礦褶皺、層間滑動構造的定量評價與預測研究 [D].北京:中國礦業(yè)大學(北京 ) ,1994 [10] 薛喜成,龍榮生 .煤礦褶皺型層滑構造的研究途徑 [R].西安:西安礦業(yè)學院,1995 [11] 鄒文康 .羅厝山井田構造特征及其對煤層厚度的影響 [J].中國煤田地質(zhì) ,2022,16(6):5860 [12] 張傳偉,錢曉虎 . 淺析孟莊煤礦層滑構造特征 [J].煤炭科技, 2022, 18( 4):2627 [13] 童宏樹,吳素珍 . 淺析前嶺井田 4 煤層層滑構造及薄化帶展布特征 [J].煤田地質(zhì)與勘探, 2022, 18(1):1822 [14] 嚴家平,姚多喜,李義良 .層間滑動構造引起煤層厚度變化特 征的研究 [J].煤炭科學技術, 1997, 25( 8): 4143 [15] 李占文,張紅果,劉旺 .云岡井田層滑構造探析 [J].煤礦開采, 2022,( 3):1113 [16] 王生全 .渭北煤田小型滑動構造特征的成因模式 [J].中國煤田地質(zhì), 1996, 8( 4): 13 [17] 傅憲章,檀雙英 .對層滑構造特征的探討 [J]煤炭技術, 2022, 19( 6): 3536 [18] 張建奎,沈佩霞,劉永峰,張云中 .登封煤田白坪井田層滑構造研究 [J].中國安徽理工大學畢業(yè)論文 煤田地質(zhì) , 2022, 17( 6): 46 [19] 徐鳳銀,徐龍,王 桂梁 .礦井層滑構造發(fā)育規(guī)律及其預測途徑 [J].煤炭學報,1995, 20( 3): 250255 [20] 琚宜文,侯泉林,姜波 .淮北海孜礦斷層與層間滑動構造組合形式及其形成機制 [J].地質(zhì)科學, 2022, 41( 1): 3543 [21] 李子明 .宿東礦區(qū)八煤層層滑構造特征探討 [J].煤炭技術, 2022, 22( 2):102104 [22] 琚宜文,王桂梁,胡超 .海孜煤礦構造變形及其對煤厚變化的控制作用 [J].中國礦業(yè)大學學報, 2022, 31( 4) [23] 張帥,劉文中,劉勝軍 .青東礦 82 煤層滑構造的發(fā)育特征 及其定量評價 [J].煤炭技術, 2022( 2): 7678 安徽理工大學畢業(yè)論文 謝辭 在論文即將完成之際,我 衷心感謝在整個論文編寫過程中 幫助我的劉文中老師,和一直在我身邊幫助我、支持我的同學們。斷裂結構面以上的 煤層,由于動力變質(zhì)的影響,煤層已發(fā)生了變化。斷裂結構面以下的煤層及夾矸,原生的層狀結構未被破壞,但有發(fā)育眾多的羽狀節(jié)理,為層間滑動的配套構造。層滑構造形式多樣,表現(xiàn)為層間滑動、揉皺破碎、伴生斷裂、伴生褶皺、穿刺構造、波狀折曲、煤層增厚薄化等。 ( 3)青東礦 主要構造線方向為 NE 向,層滑構造的主體發(fā)育方向與井田構造方向一致。巖體結構的分形研究表明, 82 煤頂板的穩(wěn)定性東部低于西部。斷層之間的交叉組合表現(xiàn)為兩組或兩組以上的斷層以一定角度疧,在井田東部表現(xiàn)為東西向斷層與北東向斷層之間的疊加形成網(wǎng)格狀;西部表現(xiàn)為北東向與北西向斷層之間的疊加呈放射狀,構成帚狀構造組合。 根據(jù) 礦井建設和生產(chǎn)的技術資料,研究了青東數(shù)以萬計層間滑動構造的發(fā)育特征及其構造煤展布規(guī)律。因其順煤巖層發(fā)生,幫在井下采掘過程中不易識別,嚴重影響采掘工作面布置和接替。有些甚至出現(xiàn)無煤帶。 ( 6)受層滑構造影響,煤層在走向上和傾向上易產(chǎn)生“ S”型彎曲。 ( 3)層滑過程 中 ,煤層頂?shù)孜鼋佑|面上,常伴有牽引現(xiàn)象。 ( 2)煤層受強烈擠壓揉皺破碎,致使滑動帶煤層結構強烈破壞。 82煤層層滑構造造成煤厚突變,形成一定范圍的不可采區(qū)或無煤區(qū),降低了煤炭儲量的可靠性,同時由于煤厚的復雜變化,加大了開采難度;在回采或掘進通過這些區(qū)域時,被迫挑頂、破底,易造 成采掘設備損壞和人身傷害,給生產(chǎn)造成嚴重影響;同時由于層滑構造造成煤層變薄、底鼓、頂?shù)装鍘r鍥穿刺及大量圍巖塊體滑入煤層等情況都會導致開采時原煤含矸率增加,嚴重影響煤質(zhì)。主要表現(xiàn)為分叉、變薄、疊置增厚等現(xiàn)象,給回采工作增加了一定的難度。 構造對煤層穩(wěn)定性的影響 層滑構造對煤層穩(wěn)定性的影響主要表現(xiàn)在對斷層厚度的影響。 引起煤厚變化的原因是多方面的,其中包括原聲變化和后生變化,前者比如聚煤拗陷基底不均衡沉降、沉積環(huán)境及古地理等的影響,后者則主要包括構造變動、巖漿侵入等英氣的煤層加厚和變薄。安徽理工大學畢業(yè)論文 22 其中,煤層厚度的變化直接影響勘查工程的密度和開采方法,是劃分煤層穩(wěn)定性的主要因素。 如圖 41 20。 圖 418 青東礦 726 工作面風巷剖面圖 ( 8)煤層增厚變薄 由滑動面兩側
