The authors think that the magmas of the intermediate-acid volcanic rocks were derived from basaltic magmas of the lower crust and are mixed magmas produced by the increase of geothermal gradients due to diapiric injection of basaltic magmas and partial melting of intermediate-basic metamorphic igneous rocks in the lower crust,and that they resulted from a series of tectonomagmatic activities that took place when the closing of the Mongolian-Okhotsk sea trough and continent-continent collision caused crustal thickening and brought about the formation of the Hinggan-Mongolian orogenic belt in the process of oblique subduction of the Paleo-Pacific plate beneath the Siberian plate.

中文摘要：通过对大兴安岭北段晚侏罗世吉祥峰组中酸性火山岩的岩石地球化学研究，发现其中存在高Sr低Y型火山岩，即文献上所称的埃达克质岩，笔者认为中酸性火山岩的岩浆起源于下地壳玄武质岩浆，为玄武质岩浆底辟上侵引起地热梯度增加、下地壳中基性变质火成岩石部分熔融的之混合岩浆，是古太平洋板块向西伯利亚板块斜向俯冲过程中，蒙古鄂霍次克海槽封闭，陆壳碰撞使地壳加厚，形成兴蒙造山带时所引起的一系列构造岩浆活动。

Crustal original and crustal\|mantle original type are located at the Yinggehai basin of the northwest margin and controlled by the diapirs up-invasion and thick marine calcic sand shales. Volcano-mantle original type is most located at the Qiongdongnan basin of the northeast margin and the Pear River Delta. Furthermore, the accumulation and migration of CO2 and oil gas of these types of CO2 are controlled by the exhaustion of mantle magma and the transportation of discordogenic faults.

壳源型和壳幔混合型CO2富集于西北边缘莺歌海走滑伸展型盆地，受控于海相含钙砂泥岩与泥底辟热流体上侵活动的物理化学综合作用；火山幔源型CO2则主要展布于东北边缘琼东南及珠江口断陷裂谷盆地，其火山幔源岩浆脱排气活动与深大断裂导气输送作用的配置，控制了这种类型CO2的运聚乃至富集成藏过程。

Considering the theory of roadway support in soft rock, we proposed an active support mode based on study of rheology of weak adjacent rock, complex stress environment, and destabilization of original supports. Fully grouted bolt, extension grouted cable that can strengthen self-bearing capacity and entirety are used. Original support scheme and reinforcement scheme are simulated by means of FLAC(superscript 3D).

The outgas types and amount of different gas resource varied with the different geological conditions and evolution processes. There are four outgas models including the model in which inorganic gas directly overflows from mantle matter through lithospheric fracture,the model of heat flow piercement outgas,the model of volcano-magma outgas,and the model of carbonate rock outgas due to heat metamorphism.

对气藏成藏条件和深部壳幔结构的研究表明，松辽盆地存在多种类型无机&气源&，由于赋存的地质条件和演化过程不同，不同气源脱气的方式、脱出气体的类型、脱气量也大不相同，共有4种主要的模式：地幔物质沿超岩石圈断裂直接脱气模式；热流底辟体脱气模式；火山—岩浆成因模式；碳酸盐岩热变质成因模式。

In orde to obtain system optimization in high efficiency production and operation safety, the microcosmic problem of goaf treatment was brought into the creative design of mining method and the synergism of two problems was studied. Firstly, in view of the occurrence characteristics and mining conditions of catacalstic ore section of orebody No. 105 in Gaofeng mine in Guangxi province, considering the adaptability to different scale goafs in the ore section, based on mining environment reconstructing idea and continuous mining mode, a new mining method (mining environment reconstructing non-pillar sublevel-strip continuous mining method) was put forward. Then, some repr, esentative goafs were selected and their stabilities were calculated by discrete element method on the basis of differences of goaf scale, surrounding conditions and situ stress field. At last, the mining layout was adjusted on the basis of goafs stability analysis and the goafs were adjusted as a part of cutting engineering, blasting space or stope, so as to determine all kinds of goafs treatment schemes.

摘 要：为在生产高效和作业安全上取得系统整体最优，将碎裂矿段的空区处理微观问题纳入采矿方法创新设计宏观问题中，开展2种问题的协同研究：首先，针对广西高峰矿105号矿体碎裂矿段的赋存特点和开采技术条件，考虑对各种规模空区适应性，基于采矿环境再造和连续采矿理论，提出采矿环境再造无底柱分段分条连续采矿法；然后，根据采空区规模、围岩状况和原岩应力场等条件的差异，在所有采空区中选择具有代表性的空区，运用离散元程序对其稳定性进行计算分析；最后，在稳定性分析的基础上，灵活调整开采布局，将采空区调整为部分切割工程、自由爆破空间或采场，从而确定出各种规模空区的处理方案。
