井田工业储量为138.29Mt,矿井可采储量85.10Mt。矿井服务年限为54.5a,矿井正常涌水量为400m3/h,最大涌水量为650m3/h。矿井瓦斯涌出量低,为低瓦斯矿井。
井田为立井单水平上下山开拓,划分为四个采区,两个采区;大巷布置在-320m水平,采区采用上、下山开采方式,采区采用集中巷布置;工作面布置为综合机械化放顶煤;大巷采用胶带输送机运煤,辅助运输采用架线式电机车牵引矿车设备,主井采用箕斗提升,副井采用罐笼提升;矿井通风方式为两翼对角式通风;矿井年工作日为330d,日提时间为16h;工作制度为“三八”制。
专题部分题目是提高煤炭采出率技术探索与实践为提升采出率并保护环境,文章介绍正常煤层赋存区的干净开采和“三下”煤层赋存区特殊开采时可供选择的几种采煤工艺。

ABSTRACT
This design includes three parts: the general part,the projects section and translation part.The general part is a new design of Xinglongzhuang coal mine.Xinglongzhuang coal mine is located in YanZhouShi,ShanDong province,the transportation is convenient.The run of the minefield is 4.3 km,the width is about 3.5 km,the total area of mine field is about 13.55km2.The three is the main coal seam, and its dip angle is 4 degree. The thickness of the main coal seam is about 8.28m in all.
The proved reserves of the minefield are 138.29 million tons. The recoverable reserves are 85.10 million tons.The designed productive capacity is 4.0 million tons percent year,and the service life of the mine is 55.4 years.The normal flow of the mine is 400m3 per hour and the max flow of the mine is 650 m3 per hour.Mine gas emission is low,for low gas mineral well.
The mine field isshaft with single level developments,devided into fout mining districts, two strip districts.The main roadway arranges in - 370m level.The mining district uses rise and dip Type,the strip district uses main inclined drift.The working face adopts fully-mechanizedcoal mining technology with sublevel caving,The main roadway uses accordion conveyor to transport coal.The auxiliary transportion uses trolley locomotive hauling mine car equipment.The main shaft uses skip hoisting,the auxiliary uses cage hoisting.The Mine ventilation mode is two-wing diagonal type ventilation.The mine pit year working day is 330d, the work routine is “four-six”.
The topic of the projects sectionisresearch on prevention and control of coal seam spontaneous combustion in the overlong fullymechanized longwall coal mining face.Base on the confirmation on the dangerous zone of seam spontaneous combustion in the overlong fullymechanized longwall coal mining face,the paper provided the related and high efficient comprehensive mine fireprevention and extinguishing technology system.A rapid emergency mine fire prevention and extinguishing system forseam spontaneous combustion fire disaster of the overlong fully mechanized longwall coal mining face wasestablished.Aseam spontaneous combustion fire disaster occurred in No. 4324 overlong fully mechanized longwall coal mining face wassuccessfully controlled,which would provide an important technical guarantee for the safety production of the overlongfully mechanized longwall coal mining face.
The main content of the translation part is about the mine pit tunnel support and protectionunder high stress soft crag under.
Keywords:The mine pit design; vertical shaftsingle level; updown a mountain mining;synthesis mechanization mining coal.
