开采

In order to find the reasons, we first investigated the distribution of the geothermal stations and the water extraction in the whole Shenzhou city and its vicinity, then investigated the oil extraction and water afflux in North China Oil Field.

为解释该趋势下降的原因，首先对深州市及其周边地区地热开采点的空间分布及地下热水开采量进行了详细调查，而后对华北油田采油和注水情况进行了了解。

Afforcement of management of coal exploit is urgent,improvement of coal exploiting efficiency and management level is in need of effective technology.

中文摘要：加强煤炭开采管理迫在眉睫，提高煤炭开采效率和管理水平急需有效的技术支持。

Thissubject exerts the experiment method of analogue modeling, and we take geologic mining condition of the Xin Zhi Colliery of Huo Zhou Mineral Bureau in Shang Xi province as the physical model of background design. The experiment is divided into two phases, the first phase simulates the course of mining subsidence, we study rule of movement transmogrification of mining terrane. In the second phase, after the mining subsidence is gradually stabilization, we bring into bear different load in the different location of subsiding basin, and we study ground stability with goaf.

本课题以山西霍州矿物局辛置煤矿地质采矿条件为例，进行了相似材料模拟试验，试验分为两个阶段：第一阶段模拟开采沉陷过程，研究采动岩层移动变形规律；第二阶段在开采沉陷基本稳定之后，在沉陷盆地的不同位置施加大小不同的建筑物荷载，研究其地基的稳定性。

Along with the ground water mining quantity increasing massively, it initiated the subsoil water level drops largely, ground water mining descended the funnel area to expand unceasingly, at present the partial region ground water burying depth has amounted to 30 - 40 meters.

随着地下水开采量的大量增加，引发了地下水位的大幅度下降，地下水开采降落漏斗面积不断扩大，目前局部区域的地下水埋深已达到30-40米。

For the exploitation of mineral resources, there are 10 species, of which, anthracite, coal-bed methane, pyrite, clay, bauxite mining stone of the most value.

可供开采的矿产资源有10余种，其中，无烟煤、煤层气、硫铁矿、粘土、矾石最具开采价值。

A coal mining in thin seam is an inevitable issue of coal mining in many coal mines.

薄煤层开采是许多矿井煤炭开采中不可避免的问题。

This paper presents a conclusion and recommendations of proper exploit the coalfield and prevent the water pouring in the mine.

在比较分析开采前后矿区渗流场变化后，提出了合理规划开采煤矿，防治井下水害的建议。

But when we mine commensuration groundwater, the falling velocity water level and range of the deep hydrous stratum are bigger than the shallow hydrous stratum. And the quantity of subsidence is not obvious different. 2. Analyzing the relation between the stratum of groundwater and land subsidence, with the depth of aquifer bed increased, the proportion that the released water because of compressibility of strata possessed become bigger, and it cause land subsidence more serious. 3. The physical and mechanical properties and the consolidation state of stratum do not become better with the depth increased.

依据： ①一般情况下，随深度增加，地层的压缩性会渐下；但是开采同量的地下水，其水位下降的速率及幅度深部含水组比浅部含水组要大的多，两者引起的沉降量不会有明显的差别；②从地下水开采资源组成与地面沉降关系分析，含水层深度越深，其中的压密释水量所占的比例也越大，造成的地面沉降也越严重；③地层的物理力学性质及固结状态，随深度的增加，也不完全是越来越好。

According to theory of diffusion and permeation,and theory of adsorpt ion equilibrium of commixture gas,the mechanism of increasing coalbed methane production by gas injection is studied, with which it is illustrated for enhancing energy of storing gas stratum, heightening pressure conduction coefficient of storing gas stratum and binging domino effect of competition adsorption by gas injection, consequently yield and ratio of recovery of coal bed methane are also enhanced.

依据扩散渗流和多组分吸附平衡理论，研究了注气开采煤层气的增产机制。研究表明，注气增加储层能量，提高储层压力传导系数并产生竞争吸附置换效应，从而提高煤层气开采时的单产量及回收率。

As the complishment of the deep exploiting of the mine ,most of them turned to be the deep exploit- ing.

随着煤矿浅部开采已基本结束，大都转向深部开采。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
