ABSTRACT: 
In order to grasp the changing situation of ground subsidence and surface collapse caused by underground mining in mining area, 
and raise the efficiency of field data collecting, this paper’s attention is paid to develop Field Collecting System Based on Wireless 
Communications to acquire spatial data and attribute data. The mobile devices use Web Services to synchronous data with the server. 
The system can get the required map from server by Map Service, it acquires high precision coordinate by making use of the GPS 
Differential Technology. The attribute data can be updated to the server by Web Services. The Field Collection System of Surface 
Deformation Information in Yanzhou Mining Area is developed on the basis of analyzing how the underground mining work affects 
the ground surface. The System will provide high precision, the lasted data for researching and monitoring the surface subsidence or 
collapse. It integrates field ascertainment and survey. That simplifies the work of data collecting and entering into the database, and 
meets the requirement of real-time data. 
1 INTRODUCTION 
The ground subsidence and surface collapse is common in the 
mining area. The major cause for surface deformation is a wide 
range of mined-out space underground caused by coal mining 
(LIU Guang, 2008). While the surface subsidence, landslides 
and other geological disasters have a serious impact on mine 
production activities and people's life, it is very important to 
know well the changing situation of ground surface for 
analyzing and predicting the change trends of ground 
subsidence, helping for adjusting the way of exploitation and 
planning of land use in the mining area, reducing the hazards of 
surface deformation. So it is necessary to design a field data 
collecting system which applies to mining area data acquisition. 
The system can acquire the position coordinate and the property 
of the surface, and it will upload the collected data to the server. 
Then the server will use this data to analyse the surface change 
trends. 
2 SYSTEM DESIGN 
2.1 Requirements Analysis 
The Field Synchronous Data Collecting System of Mining Area 
Surface Deformation Information used to collect the 
planimetric position, elevation, the potion of mined out space, 
the area, the exploitation date and the picture of mining area 
where the subsidence has occurred. And these collected data 
can be uploaded to the server for analysing. There are some 
fixed monitoring points in the subsidence area. These points are 
used to analyze the position change, especially the elevation 
change. We can use the RTK to survey these points for high- 
precision coordinate. There is a CORS station in the Yanzhou 
coal mining area, so the GPS receiver can get differential data 
from the CORS by GPRS. 
  
2.2 System Architecture 
On the server, the map spatial data is managed by the ArcSDE. 
The layers which need to be updated are published as Map 
Service. And the attribute data is stored in the Oracle. The Web 
Services are published for access the server by the mobile 
device. Figure 1 shows the architecture of Field Synchronous 
Data Collecting System of Mining Area Surface Deformation 
Information.

On the mobile device, the field data collecting system will get 
the map of the area where need to collect data from the server 
by the wireless network. Then the collected spatial data will be 
store in the map. The attribute data are stored in the embedded 
database-the SQL CE.
