试析采矿区采矿施工技术的安全控制及管理

因为大多数矿山作业地点的地理环境较为险峻,工程难度大,存在诸多不安全因素,这些安全隐患不仅对于矿山采矿工作人员生命财产安全造成威胁,还会对企业经济效益产生消极的影响,进而对采矿行业发展带来损失。因此采矿企业需要注重完善采矿安全技术管理工作,建立健全科学的条令,消除采矿作业中存在的不安全因素,降低不必要的经济损失和人员伤亡。本文将探讨采矿工程采矿技术与施工安全管理。

Study on the genesis of karstic collapse column and characteristics of high resolution seismic data in one coal field

On the standpoint of the disaster prevention from water inrush,discussed the genesis and geologic condition of karstic collapse column in one coal field,analyzed the geophysical characteristics of karstic collapse column by using high resolution 3D seismic data.It shows the effective result of the technology of high resolution 3D seismic pros- pecting in the exploration of the karstic collapse column,and presents some prediction methods and prevention measures.

Study on gob-side entry retaining technique with roadside packing in longwall top-coal caving technology

Pointed out some technical difficulties of gob-side entry retaining with roadside packing in longwall top-coal caving technology (LTCT), and analyzed the function mecha-nism of roadside filling body. Theory analysis shows the mechanical properties of high water material fit for the feature of deformation of gob-side entry retaining in LTCT, and gob-side entry retaining in LTCT face is one of effective ways to increase the recovery ra-tio of mining district.
