The Jinjiadong fluorite deposit is located on the northwest limb of the Pengshan anticlinalstructure, with the orebodies occurring in the silicified fractured zone in the Ordovician strata of Tangshan Formation Controlled by NE- sinking fault structure , the orebodies are of medium size, shallow burial depth and good quality.

The siliconizing breaking zone type of gold mine in the eastern Guangxi has been discovered, this type of gold mine was the first detection at the northside of Dayaoshan area , its prospecting significance is greatly .

After studied the Liuqiao fault fracture zone water yield property and transmissibility,pipe shed support and advance grouting reinforced engineering were adopted before the crossheading cut through the fault,meanwhile a series of tried and true driving and supporting measures taken on to insure the-380 crossheading cutting through the fault safely.

An outline is given of technical investigation of the transformed belt-subinclined shaft passing through the soft rock bed in the high stress fracture zone of Wu-er coal mountain at Level 2 of No 6 mine in Pingdingshan Coal Group Co,Ltd.

It is considered that the silicated fracture zone of carbonate rocks of the underlying Ordovician System is the mineralizing materials source of the gold deposit and the gold enrichment is relative to the extremely strong chemical weathering in tropical rainforest .

The effects of longshore currents,Stokes mass transport by waves,large scale eddies and the instability of longshore currents on the transport of pollutant in a surf zone are discussed based on the experimental results.

Technology of grouting and blocking water in fault broken zone;

Support theory and practices to repair of mine roadway in tectonic broken zone;

Study on pilot bolt reinforcement with dowelling function in project surrounding rocks of broken zone base on DDA theory
