OK - many more questions such as: Where does the mining lease end (mining leases aren't necessarily coincident with property boundaries - it is likely that the mine will stop some 10m-20m from the edge of the lease to allow for access roads and safety berms.)? What is your specific problem with the blasting? What outcome are you hoping to achieve?
You should give your local mines inspector a call - look under regional offices here: http://www.resources.nsw.gov.au/resources/contacts
Ask to speak to the mines inspector - they will be able to answer all of your questions related exactly to your property.
