Also because of the road turned to the bottom of the top players on the team at the top of the ramp, the rock loose the season still has the possibility of the Rolling Stones hit the players, Yakou the 50-100 m section of the rock surface is a monolithic block staggered zone, rock face an average of 6-7 meters high, 70-80 degrees slope is very smooth too laborious climb directly to undesirableGreat can not see well because of the snow line, and only a walk around the rock surface, in the cross section of rock surface from time to time is close to the ridge walk, the most recent is only one meter away from the cliff, and at the foot of ice or hard snow if the time is easy to slide down the ridge, more dangerous.

另外因为路线转向上方队员就在下方队员斜上方，岩石松动的季节还是有滚石击中队员的可能，垭口上50-100米路段，是整块整块的岩面交错的地带，岩面平均高6-7米，坡度70-80度，很光滑直接攀上太费力不可取，由于雪大看不出好的路线，只有绕着岩面走，在跨越岩面时有部分路段是贴着山脊走，最近的离悬崖仅一米，而且脚下如果结冰或者是硬雪时很容易滑下山脊，比较危险。

On the basis of the geological engineering conditions and rock mass quality classification, the change of wave speed of rock mass is used to analyze systematically the control of dissolution of calcareous sandstone over rock mass quality. The modificatory standard of rock mass quality classification was bring and the system of rock mass quality classification in the hydroelectric station.

论文在坝址区工程地质条件评价及岩体质量分级的基础上，利用岩体弹性波速的变化，深入研究了钙质砂岩溶蚀对岩体质量的控制作用，提出初步的岩体质量分级修正标准，得到坝区的岩体质量分级体系。

The first type is different kinds of rocks including sedimentary rock, metamorphic rock and volcanic rock among which black mudstone, black shale, clay, slate, phyllite, granite, basalt, andesite and volcanic ash are the best except some chemically depositional rock such as salt rock, gypsum, limestone.

第一类是自然界各种不同类型的岩石，包括沉积岩、变质岩和火山岩，其中以黑色泥岩、黑色页岩、粘土、板岩、千枚岩、花岗岩、玄武岩、安山岩及火山灰为最佳，但不包括某些化学沉积岩，如盐岩、石膏、石灰岩。

Analyze the failure models of rock slope, and then classify the sliding plane, the sliding plane can be divided into self-born sliding plane, appendiculate sliding plane and mixed sliding plane, furtherly summarize the selection method of mechanics parameters to each types. Based on the classification, the author establishes the mechanics model of each sliding plane. Discuss the influence of water and weathering and sedimentation conditions on rock slope, and then specify the geological cause of rock bedding slope, counter-tilt rock slope and cracked rock slope.

2分析了岩质边坡的几种主要破坏模式，在此基础上对岩质边坡滑动带进行分类研究，从大的方面主要分为自生型滑动面、依附型滑动面和混合型滑动面三类，总结与各类滑动面相适应的力学参数取值方法，从而建立岩质边坡滑动面的力学分析模型，讨论水、风化和沉积环境对岩质边坡的影响，归纳了顺层岩质边坡、反倾岩质边坡和破碎岩质边坡滑动面的成因。

The strength of coal and rock mass can be weakened through deep hole relieving shot, so the ability of energy accumulation is reduced, and a large amount of elastic energy accumulated in coal and rock mass is released, which makes it sure that the elastic energy accumulated in coal and rock mass do not exceed the minimum energy induced rock burst. Simultaneously, electromagnetic emission is used to check out the effect of eliminating or reducing the danger of rock bursts.

通过深孔卸压爆破来弱化煤岩结构的强度，降低其聚能能力，释放所积聚的大量弹性能，使得煤岩体中所积聚的弹性能达不到最小冲击能；同时利用电磁辐射检验强度弱化治理效果，以达到消除或降低冲击危险的目的。

Next, take the rock mechanics as a foundation, has analyzed the gas drilling broken rock mechanism; Thought that the gas drilling broken rock mechanism is different with the conventional drilling fluid well drilling, the bottom of the well rock destruction way destroys for the volume, the bottom of the well rock and the drill bit contact plane disproportionality causes the gas well drilling well diviation another reason.

其次，以岩石力学为基础，分析了气体钻井破岩机理；认为气体钻井破岩机理不同于常规钻井液钻井，井底岩石破坏方式为体积破坏，井底岩石与钻头接触平面不均衡性是导致气体钻井井斜的又一原因。

Based on isotopic ages and the cycle of magamtism, the ages of Yanbian granites can be subdivided into five periods:①late Permian granites (260-245Ma), the typical plutons are Liukesong and Liangbing plutons, and the main rock type include diorite-monzonitic-K syenogranites;②Triassic granites (225-200Ma), the typical plutons are Sandaogou, Chunyang, Qishiergedingzi, Dahuanggou, Naozhi, and Qinglinzi plutons, the main rock type include quartz dioritesgranodiorites-monzonitic-alkali granites;③early Jurassic granites (190-180Ma), which composed of quartz diorites-granodiorites - monzonitic ,and the typical plutons are Shimen, Miantian, Daxinggou and Yushuchuan rock;④Middle-Late Jurassic (170-150Ma), which composed of granodiorites- monzonitic- garnet-bearing muscovite granites, the typical plutons are Huangniling, Weizigou, Loutuoshan and Dongqing rock;⑤early Cretaceous (about 130Ma), the typical pluton is Zhongping pluton, and its rock type is paulite diorite.
