         2 . The intelligent mine device of  claim 1 , wherein the detection unit comprises a magnetic field sensor that detects the approach of the target object via the Earth' magnetic field. 
     
     
         3 . The intelligent mine device of  claim 1 , further comprising:
 a storage unit that stores group information about intelligent mine devices that are grouped,   wherein the blasting unit is further configured to generate a blasting instruction for the blasting of the intelligent mine devices that are grouped and provide the blasting instruction to the intelligent mine devices that are grouped through a radio communication in order to blast the intelligent mine devices that are grouped.   
     
     
         4 . The intelligent mine device of  claim 3 , further comprising:
 a grouping unit configured to radio-communicate with at least one or more intelligent mine devices within a predefined radius to generate the group information about the intelligent mine device that are grouped as the intelligent mine device is initialized.   
     
     
         5 . The intelligent mine device of  claim 2 , wherein the blasting unit blasts the intelligent mine devices that are grouped in a sequential or simultaneous manner depending on the blasting instruction. 
     
     
         6 . The intelligent mine device of  claim 5 , wherein the blasting unit is further configured to transmit the blasting instruction to the intelligent mine devices that are grouped, and
 wherein the blasting instruction contains information on a blasting time.   
     
     
         7 . The intelligent mine device of  claim 1 , further comprising:
 a message generating unit configured to generate an identification message to make a request for an entry of a cryptogram as the target object approaches, the identification message being sent to the target object,   wherein the analysis processing unit is further configured to receive a reply to the identification message for a predetermined period of time and compare information in the received reply and a pre-stored cryptogram to identify whether the target object is a friend or foe.   
     
     
         8 . The intelligent mine device of  claim 1 , further comprising:
 a message generating unit configured to generate an identification message to make a request for an entry of a cryptogram as the target object approaches, the identification message being sent to the target object,   wherein the analysis processing unit is further configured to identify whether the target object is a friend or foe depending on the presence or absence of a reply to the identification message for a predetermined period of time.   
     
     
         9 . A method for operating intelligent mine devices, the method comprising:
 generating group information about neighboring intelligent mine devices within a predefined radius as the intelligent mine devices are initialized;   detecting that a target object approaches;   performing a radio communication with the target object to identify whether the target object is a friend or foe; and   transmitting a blasting instruction to the intelligent mine devices in the group information in order to blast the intelligent mine devices in the group information when the target object is identified as the foe.   
     
     
         10 . The method of  claim 9 , wherein said detecting that the target object approaches comprises detecting the approach of the target object via the Earth' magnetic field. 
     
     
         11 . The method of  claim 9 , wherein said generating group information comprising:
 radio-communicating with the intelligent mine devices within the predefined radius to generate the group information.   
     
     
         12 . The method of  claim 9 , wherein said identifying whether the target object is a friend or foe comprising:
 sending an identification message for identification of friend or foe to the target object using a radio communication; and   performing the identification of friend or foe depending on a reply message to the identification message.   
     
     
         13 . The method of  claim 9 , wherein said identifying whether the target object is a friend or foe comprising:
 generating the identification message to make a request for a cryptogram to send the identification message to the target object; and   upon receiving a reply message to the identification message for a predetermined period of time, comparing information in the received reply and a pre-stored cryptogram to identify whether the target object is a friend or foe.   
     
     
         14 . The method of  claim 13 , wherein said identifying whether the target object is a friend or foe comprising:
 initializing a predetermined count;   increasing the count when the reply message is not received or the information in the reply message is not identical to the pre-stored cryptogram;   retransmitting the identification message when the count is less than or equal to a predetermined threshold value; and   identifying the target object as the foe when the count is not less than or equal to the predetermined threshold value.   
     
     
         15 . The method of  claim 9 , wherein said identifying whether the target object is a friend or foe comprising:
 sending the identification message containing a request for performing a given operation to the target object; and   performing the identification of friend or foe depending on the presence or absence of a reply message to the identification for a predetermined period of time.   
     
     
         16 . The method of  claim 15 , wherein performing the identification of friend or foe comprising:
 initializing a predetermined count;   increasing the count when the reply message is not received;   retransmitting the identification message when the count is less than or equal to a predetermined threshold value; and   identifying the target object as the foe when the count is not less than or equal to the predetermined threshold value.   
     
     
         17 . The method of  claim 9 , wherein said blasting the intelligent mine devices comprising:
