Modifies standards relating to mining practices

HB 704 modifies Missouri mining regulations by requiring mining operations in cities, towns, or villages with 1,000+ residents to obtain and file an indemnity bond before starting work. It also mandates 30 days' public notice through local newspaper publication or posted handbills for proposed mining activities, detailing the location and nature of operations. The bill establishes procedures for surveying underground drifts that cross property lines, including penalties for obstructing surveys. It defines key terms like "mining," "metallic minerals," and "affected land" to clarify regulatory scope. The law directly affects mining companies operating in incorporated municipalities with significant populations.
