In order to perfect the theoretical system of "tectonic control of hazard", this thesis researches the control function of stratum inclination of monoclinic structure, fold shape and angle between two limbs of fold, normal fault direction of dip and fault inclination, forms of faults combination over coal-mining-induced subsidence by means of theoretical analysis and numerical testing.

为了进一步完善&构造控灾&理论体系，本文从典型煤矿区的地质条件和开采实际出发，在以往研究成果的基础上，通过理论分析和计算机数值试验，重点研究单斜构造的地层倾角、褶皱构造形态及其翼间角、正断层倾向和倾角及断层组合对采煤沉陷的控制作用。

Adopting survey technology of double-head water-stopped machine flowing high of upward-inclined drillhole rock destruction rules were survey ed,development height of water conducted zone was gained.

采用井下仰斜钻孔双端堵水器导高观测技术对白庄煤矿综放开采条件下，覆岩破坏规律进行了实测，得出了导水断裂带的发育高度。

The high rotten coal (including the anthracite and meager coal ) radioactive level is relatively low,( 238U: 29.1Bq/kg , 232Th: 25.9Bq/kg , 226Ra: 37.5Bq/kg), obviously lower than the radioactive levels of the brown coal and bituminous coal, and fluctuating range little relatively stable until Lincang uranium germanium colliery HeKai Tian little dragon's pool power plant make , investigate than right far correctly, prove natural radioactive nuclide (238U , 232Th , 226Ra ) than activity transformation in the course of utilizing and give locality radiate influence that environment bring.

高变质煤放射性水平相对较低，（238U：29.1Bq/kg、232Th：25.9Bq/kg、226Ra：37.5Bq/kg），明显低于褐煤和烟煤的放射性水平，且波动范围较小、相对稳定通过对临沧铀锗煤矿田和开远小龙潭电厂作出调查比对，说明了天然放射性核素（238U、232Th、226Ra）比活度在利用过程中的转移以及给当地放射环境带来的影响。

In accordance with the characteristics of coal mining main drainage pump and present state of control and measurement technology,this paper introduces a kind of modularized control and measurement system for coal mining main drainage pump .

In accordance with the characteristics of main drainage pump for coal mine and the present development of control and measurement technology, the paper introduces a kind of modularized computer monitoring system for main drainage pump underground coal mine.

针对煤矿主排水泵的特点和当前测控技术发展，本文介绍了一种基于模块化的煤矿井下主排水系统计算机监控系统。

This design basis of the provided by the bureau surveying place normal and the largest yield,by "Coal Mine Safety Regulations" and the design specification,atter a scientific calculation and analysis,carry on the choice in view of the drainage pump and the discharge pipe to calculate and to verify.

根据局地测处提供的正常和最大涌水量，按《煤矿安全规程》和设计规范的要求，经过科学的计算和分析，针对排水泵和排水管进行了选择计算并校验。

I will endeavour to find you some assistance.
