Dongziya Tunnel DK683 +938 ~ DK684 +076 segment is with Dukang groove fault fracture zone, in which the DK683 +938 ~ DK684 +004 segment is shallow-buried. Shallow-buried depth of tunnel, fractured,rock of tunnel are apt to cause vault subsidence, horizontal convergence, collapse in excavation progress.

洞子崖隧道DK683+938～DK684+076段属杜康沟断层破碎带，其中DK683+938～DK684+004段为浅埋段，隧道埋深浅、围岩较破碎，施工中易出现拱顶下沉、水平收敛、坍塌等现象。

Temporary support, anchored grouting and enhanced water diversion and discharge are taken to solve the subsidence of water-saturated shallow-depth fracture zone vault of Haozhuang Tunnel along Tongchuan-Huanglin first-class highway.

为了解决铜川—黄陵一级公路蒿庄梁隧道富水破碎带拱顶下沉问题，采用了加强临时支护、吉迈式锚杆注浆、加强引排水等措施进行了治理，有效地固结了断层破碎带，形成应力圈，控制住下沉，解决了淋滴水和漏水问题，处理效果较为理想。

When the installation of steel liner plate broken when the cavity, as a result of steel-lined plate to absorb the energy of the material than the rock from the lining of the energy absorption is much less, so more efficient fragmentation.

当破碎腔内安装钢衬板时，由于钢衬板对物料能量的吸收要比石层自衬对能量吸收小得多，因此破碎效率较高。

Before crushing, the crusher shall be cleaned by the same origin washing sample of this Nickel Ore, and then swept with brush. After crushing, the remained sample shall be completely removed so as not to contaminate the next one.

破碎前需用本批镍矿同一来源的冲刷样品对破碎机进行清洗，然后再用毛刷等工具清扫干净，破碎后残留在破碎机内部的样品，必须全部取出，防止污染下一个样品。

Mountain water company in the March 2, 1984 in South Korea to set up a registered capital of 31 million U.S. dollars; August 1991 in the Korean stock market listing, the South Korean government is supporting the company one of the main products include: lorry cranes, hydraulic broken Hammer, hydraulic shear, Daben machine, fast connectors, hydraulic grab, special vehicles, such as rock-breaking system, the products are exported to more than 100 countries and regions, sales cover the rest of the world.

水山公司于1984年3月2日在韩国成立，注册资金3100万美元；1991年8月在韩国股票市场上市，是韩国政府扶持的公司之一；主要产品包括：随车起重机、液压破碎锤、液压剪、打夯机、快速连接器、液压抓斗、特殊车辆、等离子岩石破碎系统，产品远销100多个国家和地区，销售范围遍及世界各地。

The measurement and analysis of recess by tri-cone bit teeth and bottom-hole pattern is an important link of drilling test,a key means of studying rock-breaking mechanism,and valuating rock-breaking efficiency.

以三牙轮钻头上单齿圈为对象进行试验，研究钻头破碎岩石后得到的破碎坑。

The products are principally used to crush limestone, shale powder sand, rock, gypsum, coal and other materials whose compressive strength is not more than 200 Mpa in mining, cement, building materials, chemical industry.

该产品主要用于矿山、水泥、建材、化工等行业破碎抗压强度不大于200Mpa的石灰石、泥质粉砂石、岩石、石膏、煤等物料的破碎。

The results are as follows: 1 great changes have taken place in land use and landscape pattern from 1995 to 2000; the area of woodland, water and unused land has been reduced and that of grassland, cropland and construction land increased; 2 the advance of fractal dimensions, the diversity index and landscape fragmentation degree showed that landscape units became strongly fragmented; 3 the dominant degree of construction and unused land has changed little but that of meadow and water increased, and that of farmland and woodland decreased to some extent, which indicated that the trend of landscape pattern changed from cropland and woodland to meadow and water; 4 the changes of land use and landscape patterns near the road are obvious and it is urgent to strengthen eco_environment protection.

主要结果如下：①1995-2000年间，研究区土地利用变化显著，其中林地、水域和未利用土地面积下降，而草地、耕地和建设用地面积增加；②景观破碎化程度加剧，分维数、多样性指数和景观破碎度均增加；③建设用地和未利用土地优势度变化不大，耕地和林地的优势度减小，草地和水域优势度增加，表明研究区景观格局由耕地、林地向草地和水域转变；④交通干线附近的土地利用和景观格局变化显著，加强这些区域的生态环境保护与建设势在必行。
