In turning point and anticlinal p1unging portion -microfracture development and low stress area,it is favorable to prospect a coalbed gas.
但由于煤的变质程度较低,煤质较差,加上逆掩断裂的挤压作用,使地层有效地应力较高、造成煤储层渗透性较差;再者,煤储层的含气饱和度较低,开煤层气的产出较为不利;但在构造的转折端及背科的倾伏部位,存在着微裂隙较发育的地应力低带,有希望找到煤层气勘探开发的有利区。

Objective To investigate the clinical features, causes of blindness and diagnosis of Vogt Koyanagi Harada syndrome Methods The data of 157 patients with VKH syndrome were reviewed and analyzed Patients were carefully examined with slit lamp, ophthalmoscope, three mirror lens, fundus fluorescein angiography, indocyanine green angiography and HLA typing Results Headache was noted in 73 5% of these patients Simultaneous involvement of both eyes occurred in 80 8% of these patients Chroiditis,papilledema and edema of the retina adjacent to the optic nerve were noted in 100% of these patients in the posterior uveitis stage, whereas recurrent granulomatous anterior uveitis (98 4%),"sunset glow" fundus (95 8%) and Dalen Fuchs nodules (71 2%) were the common ocular findings in the recurrent anterior uveitis stage The common causes of blindness were papillitis, exudative retinal detachment and complicated cataract in the posterior uveitis stage, anterior uveal involvement stage and its recurrent stage Poliosis (36 3%) and alopecia (35 0%) were the most common extraocular findings Early irregular patches of fluorescence, followed by localized hyperfluorescent spots were the typical findings of FFA Dilation of choroidal vessels and leakage of ICG from the choroidal vessels were the common ICGA findings The prevalence of HLA DR4 and HLA DRw53 in patients (54 9% and 71 8% respectively) was significantly higher than that in controls (14 7% and 38 2% respectively) Conclusions VKH syndrome is characterized by chroiditis, papillitis or neuroretinitis in the posterior uveitis stage, followed by a generalized uveitis with a typical recurrent granulomatous anterior uveitis Extraocular findings and relevant examinations including FFA, ICGA and HLA typing are helpful to the diagnosis of VKH syndrome
目的探讨Vogt-Koyanagi-Harada综合征患者的临床特征、盲目原因及诊断等有关问题。方法对在1996年1月至2000年12月间就诊资料完整的157例VKH综合征患者进行回顾性分析,并对裂隙灯、眼底镜、三面镜、荧光素眼底血管造影(fundus fluorescein angiography,FFA)、吲哚青绿血管造影(indocyanine green angiography,ICGA)及人类白细胞抗原分型等检查结果进行分析。结果 VKH综合征最常见的前驱症状为头痛(102例,73.5%),双眼同时患病118例(80.8%);后葡萄膜炎期眼部主要表现为脉络膜炎、视乳头及附近视网膜水肿(100.0%);前葡萄膜炎反复发作期眼部表现为复发性肉芽肿性前葡萄膜炎(128例,98.4%)、晚霞状眼底改变(95.8%)及Dalen-Fuchs结节(71.2%);后葡萄膜炎期、前葡萄膜受累期及前葡萄膜炎反复发作期导致盲目的主要原因分别为视乳头炎、视网膜脱离及并发性白内障;毛发变白(36.3%)及脱发(35.0%)是最常见的眼外表现;炎症活动期FFA典型表现为斑驳状高荧光,ICGA发现脉络膜血管扩张、通透性增高等改变;VKH综合征患者HLA-DR4及HLA-DRw53的阳性率(54.9%及71.8%)显著高于正常对照组(14.7%及38.2%)。结论 VKH综合征患者在后葡萄膜炎期眼部典型表现为双侧脉络膜炎、视乳头炎或神经视网膜炎,随后出现以反复发作的肉芽肿性前葡萄膜炎为特征的全葡萄膜炎。眼外症状及相关的辅助检查包括FFA、ICGA 及HLA分型等有助于VKH综合征的诊断。

Taking the eastern sag of the Liaohe basin where coal, oil and gas resources coexist and the Wangying borefield of the Fuxin basin where coalbed gas was first discovered, researched and developed in China as examples, we systematically discuss the control of volcanism on the lateral and vertical distribution of brown coal, flame coal and gas coal in the third member of the Paleogene Shahejie Formation and on the gas source conditions of each coal region. Both the methane released in the process of regional plutonic metamorphism and the additional methane generated by contact metamorphism are calculated. The physical properties and storage capacity of the coal beds changed greatly due to the formation of blackcoal and highlymetamorphosed crevice coal from igneous intrusion. The sealing capacity of intrusions with various occurrences such as dikes is highlighted.

It is embodied concretely:(1) With the adoption of grouting bolts, the cranny in wall rocks can be blocked up, the air can be isolated, the wall rocks can be prevented to be weatherized and make water, the strength of wall rocks can also be avoided to be lowered;(2) The lax broken wall rocks are commentated to a whole by liquid after they were grouted and the rock"s strength is increased, so the wall rocks become a part of the support structure by using itself and become a whole with the original rock, and the roadway is made to keep stable but not easy to be broken;(3) The spray layer wall are filled with liquid after grouting, the stress is avoided to be concentrated because the load could be evenly acted on the spray layer and the support;(4) The pressure acted on the plank can be delivered to the two sidepieces and then to the bottom by reinforcing the sidepiece; At the same time, the concentration degree of loads acted on the motherboard can be weaken because of the enlargement of the combination arch"s thickness, as result, the rock"s stress is lowered and the heaving is alleviated;(5) The common bolt is made to be fixed the whole length after grouting, the layers are connected to a integral whole and bear the weight of loads, so the support structure"s unity is increased.
具体体现在:(1)采用注浆锚杆注浆,可以利用浆液封堵围岩裂隙,隔绝空气,防止围岩风化,且能防止淋水和渗水,避免围岩被水浸湿而降低围岩的本身强度及造成的巷道变形。(2)注浆后浆液将松散破碎的围岩胶结成整体,提高了岩体强度,实现利用围岩本身作为支护结构的一部分,且与原岩形成一个整体,使巷道保持稳定而不易产生破坏;(3)注浆后使得喷层壁后充填密实,保证荷载能均匀地作用在喷层和支护上,避免出现应力集中点而首先破坏;(4)注浆后使作用在顶板上的压力能有效地传递到两帮,通过对帮的加固,又能把荷载传递到底板;同时由于组合拱厚度的加大,这样又能减小作用在底板上的荷载集中度,从而减小底板岩石中的应力,减轻底臌;(5)注浆加固后能使普通端锚锚杆实现全长锚固,它们共同将多层组合拱连成一体,共同承载,提高了支护结构的整体性。

To fulfill his declared goal of scrutinizing "the cracks in the granite of genius," Garff quotes at length from Kierkegaard's 62 journals, as well as from the "theological torpedo" that the "anticlerical warrior" launched with scores of diatribes against "cultural Protestantism" and organized Christianity in the last year of his life.

While laybacking up the lower section of the crack, I concentrated on conserving my energy by climbing as fluidly and in as relaxed a manner as possible. I felt surprisingly strong through the first series of difficult moves, but as I began to execute one of the last ones, my timing and body position were slightly off. As I tried to thrust my finger tips into a small undercling slot, my foot popped off and I suddenly found myself dangling 2000 feet above the ground.
在裂隙下面部份要layback上时,我专注的尽量流畅和用放松的方法来节省体力,我觉得自己好像惊人的强壮爬完第一个连续难点,但当开始爬最後一个时,我的步调及动作有点不配合,我试著强把指尖放进一个小倒拉缝时,脚砰的滑掉,突然觉得自己在距地面二千英尺的地方摆荡。

Analyses of the relationship among strength factor, structure and reservoir permeability show that the high permeability zones of the No.3 coal seam in the Shanxi Formation of CBM development blocks in the southern Qinshui Basin commonly occur in the fold axial region with a low strength factor and relatively strong deformation of rock mass, especially the superimposition region of multistage fold axes, where strong deformation resulting in welldeveloped fractures in coal seams.
