Description
Technical field
The invention belongs to coal resources underground mining technologies field, it is related to a kind of stope overlying strata activity control method, especially
It is related to stope overlying strata activity control method under a kind of coombe landform based on remote sensing monitoring.
Background technology
Coal is the basic energy resource and important source material of China, accounts for more than the 90% of China's fossil energy resource, is stable, warp
Ji, the self -support degree highest energy.Proportion of the coal in primary energy consumption will be gradually reduced, but in quite long-term
Interior, the main body energy position of coal will not change.At present, China coal industry has been enter into " fourth phase simultaneously deposits " (demand slowdown in growth
Phase, superfluous production capacity period of digestion, environmental constraints reinforcing phase, structural adjustment are assaulted fortified position the phase) developing stage.Because China is based on coal
Energy resource structure short-term in be difficult to change, therefore build intensive, safe efficient, green Modern Coal industrial system, ensure
National energy supply security, promotes the healthy and stable development of social economy, with highly important strategic importance.
While coal is that tremendous contribution is made in human civilization and social progress as a kind of fossil energy, mining area band is also given
Eco-environmental damage problem is seriously carried out, such as coal mining triggers surface subsidence, the circulation of destruction ground water regime, environment of mining area
By waste pollution etc..The conspicuous contradiction of exploitation of coal resources and ecologically environmental restriction has caused the attention of State-level,《In
Magnificent the 13rd 5 years (2016-2020) planning outline of people's republic's national economy and social development》In clearly propose " ...
Carry forward vigorously Coal Clean efficiently to utilize, limitation east, control middle part and northeast, optimization west area Coal Resource Development are pushed away
Enter the greenization exploitation of Large-scale Coal base and transform ... "；And《Dissertation of Development of Coal Industry " 13 " (2016-2020) is planned》In
Propose again " ... Green Development theory is firmly established, carries out Coal Green exploitation, development of coal dressing of coal by washing, development mining area is followed
Ring economy, strengthens mining area ecological environment and administers, and promotes coal supply revolution ... ".In recent years, the center of gravity of coal resources in China exploitation
Therefrom east is transferred to the fragile Arid＆semi-arid area of western eco-environment soon, and formd northern Shensi, yellow Gansu Province, Shen Dong,
The northwest such as Ning Dong, Xinjiang Large-scale Coal base.The typical natural endowment characteristic in NORTHWEST CHINA mining area coal seam is that thickness is big, buries shallow, base

The main mining areas such as the NORTHWEST CHINA Inner Mongol, Shaanxi and Shanxi are generally ancient coombe development mining area, and coombe is the one of earth's surface
Plant erosion landform.Area is developed in coombe, surface vegetation is sparse, and water and soil conservation ability is weaker.Relative to Plain mining area, coombe hair
Educate crisscross and fluctuations topography and geomorphology and influencing each other for underground mining activity in mining area more sensitive and violent.With
Exemplified by the mine of the Dongsheng, Inner Mongolia mining area middle and south, the regional coal-seam buried depth is generally between 60~150m, and ocurrence of coal seam is steady
Fixed, mining conditions are superior.However, found at the scene during engineering practice, due to the ancient coombe development impact of the region earth's surface,
Abnormal ore deposit pressure is often showed during the working face mining of most of mines and shows phenomenon.For example, working face is just normally opened
Occurs the outstanding top of top plate large area during adopting and intensity occurs suddenly for very tardy raw first weighting, working face more than first weighting
Abnormal period causes large area roof fall phenomenon to press and irregularly occur the unexpected unstability of coal column.A variety of off-notes show,
Under coombe landform during shallow coal scam, the various coombe slopes of earth's surface occurrence make the working face in the pit strata-pressure behavior be in
Reveal new feature, efficiently produced to mine safety and cause adverse effect；Meanwhile, underground mining activity, which makes just to rise and fall originally, to be become
The earth's surface of change becomes more incoherent, even results in earth's surface and deforms upon disaster.
At present, for the research of shallow coal scam under coombe landform, strata-pressure behavior, stress field point are rested on mostly
In terms of cloth feature, stope overlying strata movement law and the analysis of working face pressure rack disaster reason.Existing correlative study is often individual
The roof Control Technology do not dug up mine under geological conditions not specifically, its field application limitation is big, is not suitable for various abnormal ore deposit pressures
Show phenomenon.It would therefore be highly desirable to invent stope overlying strata activity control method under a kind of coombe landform based on remote sensing monitoring.
